The discovery of 78,000-year-old Neanderthal footprints on a Portuguese beach is yet another blow to creationist pseudoscience. Preserved in the ancient sands of Monte Clérigo, the tracks of an adult male, a child, and a toddler walking together paint a vivid picture of Neanderthal life — not as brutish subhumans, but as highly social beings living in complex family groups, navigating diverse coastal environments long before modern humans entered Europe. Such findings are not only consistent with the evolutionary timeline but utterly irreconcilable with young-Earth creationist beliefs.

According to mainstream geological dating techniques, these footprints were made tens of thousands of years before the supposed biblical date of creation (around 6,000 to 10,000 years ago, depending on interpretation). For creationists who insist that all of Earth’s history must be crammed into a few millennia, these kinds of discoveries are profoundly inconvenient. Worse still, the clarity of the evidence — physical impressions in sediment, dated using well-established methods like optically stimulated luminescence — makes them difficult to hand-wave away.

Faced with such a challenge, creationists will likely fall back on a familiar toolkit of denial strategies. Some will try to cast doubt on the dating methods, resorting to pseudoscientific critiques of OSL or claiming unknown “contamination” skewed the results. Others may assert that the footprints were made after Noah’s Flood — an idea that stretches credulity beyond breaking point given the age and geological context. And, of course, some will simply ignore the evidence altogether, pretending it doesn’t exist or insisting that Neanderthals were just humans who lived in “post-Babel dispersion” times, despite the overwhelming fossil, genetic, and archaeological data to the contrary.

The discovery has been reported recently in the journal Scientific Reports by a team of researchers which includes experts from the Gibraltar National Museum and the University of Lisbon, Portugal.

Scientists Find the First Ice Core From the European Alps That Dates Back to the Last Ice Age - DRI

It never rains but it pours for creationism. Or in this case, not pouring rain but a veritable ice storm — an ice core from the oldest Alpine glacier, holding a remarkably detailed record of the past 12,000 years, stretching back to the end of the last Ice Age.

The core, 40 metres long, was extracted from Mont Blanc’s Dôme du Goûter glacier in the French Alps.

And — surprise, surprise! — there is no sign of a cataclysmic global flood. Not even the faintest trace. In this part of the French Alps at least, the worldwide genocidal flood that creationists believe their deity unleashed upon the Earth quite simply never happened. Strangely, a flood supposedly deep enough to cover all mountains (Genesis 7:19–20) failed to reach the peaks of the European Alps.

Instead, what the ice core reveals is a continuous, uninterrupted history stretching back to at least 2,000 years before ‘Creation Week’, capturing seasonal changes, shifts in climate, volcanic eruptions, and even Saharan dust storms—each leaving a tell-tale signature now entombed in successive layers of ice.

Even more awkward for creationists is the fact that this ice-core record aligns precisely with well-documented events elsewhere, allowing scientists to calibrate and extrapolate timelines deep into European prehistory with high accuracy.

Creationism Refuted - Tree Pollen Record - from 140,000 Years Before 'Creation Week'

Tree pollen reveals 150,000 years of monsoon history in Northern Australia – News

Droughts in Southeast Asia and increasingly devastating floods in Northern Australia are not random anomalies—they are predictable consequences of climate change, as revealed by a 150,000-year record of monsoon patterns preserved in tree pollen from sediment in Girraween Lagoon near Darwin. This record, meticulously analysed and correlated with evidence of past climate change and ocean currents, offers a stark warning about what lies ahead.

Not only does this research thoroughly dismantle the juvenile creationist fantasy that Earth is a mere 6,000 to 10,000 years old, it also flatly contradicts the myth of a global flood just a few thousand years ago—such a cataclysm would have obliterated the very sediment that preserved this climate history. Moreover, it challenges the simplistic notion that Earth was "finely tuned" for life, since the data show a planet subject to instability and extreme hardship, at times rendering regions locally uninhabitable due to global climatic shifts.

The study, conducted by researchers at James Cook University and Flinders University, demonstrates that shifts in Northern Australia's monsoon patterns coincide with Heinrich events—sudden surges of cold meltwater into the North Atlantic that weaken the Gulf Stream. As the Gulf Stream drives much of Western Europe’s climate by transporting warm water across the Atlantic, its disruption would have profound consequences for Europe as well.

Can you tell me more about these Heinrich events, please. Heinrich events are dramatic climatic episodes that occurred during the last glacial period, named after marine geologist Hartmut Heinrich who first identified them in the 1980s. These events represent sudden and massive discharges of icebergs into the North Atlantic Ocean, originating primarily from the Laurentide Ice Sheet in North America.

Key Features of Heinrich Events:

1. Ice-Rafted Debris (IRD):
   Heinrich events are identified by layers of sediment in North Atlantic marine cores that contain ice-rafted debris—fragments of rock and other materials carried by icebergs and dropped onto the seafloor as the ice melted.
2. Abrupt Cooling:
   The influx of cold, fresh meltwater into the North Atlantic during a Heinrich event disrupted thermohaline circulation (the so-called Atlantic Meridional Overturning Circulation, or AMOC), particularly the Gulf Stream. This led to abrupt regional cooling, especially in Europe and North America.
3. Duration and Frequency:
   These events occurred roughly every 7,000–10,000 years during the last glacial cycle (~70,000 to 10,000 years ago), though the exact timing and spacing varied. Each event may have lasted for several hundred to a few thousand years.
4. Global Impact:
   Although triggered by North Atlantic dynamics, Heinrich events had global repercussions. Evidence shows climate responses as far afield as the Indian monsoon, tropical Africa, and South America, where rainfall patterns shifted dramatically. The study you linked to adds Northern Australia to that list, showing that these events influenced monsoons far from their origin.
5. Mechanism:
   The most widely accepted model suggests that internal ice-sheet instability or subglacial processes triggered massive iceberg calving events. These icebergs melted in the North Atlantic, introducing vast amounts of fresh water and lowering ocean salinity. This in turn weakened or shut down deep-water formation, a key component of the global climate system.

---

Summary:

Heinrich events are natural examples of abrupt climate change—rapid and severe disruptions to the climate system caused by shifts in ocean circulation. They provide a powerful lesson for today: large-scale climatic systems can change quickly and globally in response to disturbances, especially involving the ocean’s role in heat and moisture distribution.

The team's findings are now published in Quaternary Science Reviews, and are also explained in lay terms in a Flinders University blog post.

Tree pollen reveals 150,000 years of monsoon history in Northern Australia

---

Northern Australia’s annual monsoon season brings relief to drought-stricken lands and revitalises crops and livestock for farmers. But a study of 150,000 years of climate records shows that the monsoon is likely to intensify, triggering a higher risk of flooding while worsening the impact of droughts in East Asia.

---

Led by Professor Michael Bird, researchers at James Cook University and Flinders University have assessed sediments at Girraween Lagoon near Darwin, revealing a continuous record of monsoon rainfall patterns dating back beyond the last interglacial period.

This research published in the scientific journal Quaternary Science Reviews offers insight into how climate change could alter monsoon patterns across East Asia and Australia.

This is the longest terrestrial record ever produced at the southern end of the Indo-Australian monsoon system, which delivers vital rainfall to millions across the Southern Hemisphere. The record also has implications for the Northern Hemisphere where tens of millions in Asia rely on monsoons for food and their livelihoods.

Our study shows how the two monsoon systems are interrelated over thousands of years and reveals what causes them to change. Our analyses shows that that rainfall in northern Australia is closely tied to sea level changes, which shift the location of the northern coastline by up to 320 km.

These shifts strongly alter local rainfall, with wetter periods occurring when the coastline is closer to the Australian landmass and the oppose effect is prolonged drought in East Asia.

Intriguingly, the research also uncovered what we consider bursts of intense monsoon activity — some lasting less than 10,000 years. These bursts align with Heinrich events — abrupt pulses of freshwater into the North Atlantic from rapidly melting ice linked to the weakening of the Gulf Stream in the Atlantic Ocean.

These findings carry a warning from scientists because the Gulf Stream is already weakening due to climate change, and the study suggests this could lead to increased rainfall in northern Australia while contributing to droughts in parts of East Asia.

This isn’t just ancient history. It is a window into the rainfall patterns that are emerging today. Our data suggest that the weather trends we’re witnessing like the drying in China and wetting in northern Australia could accelerate if the Gulf Stream continues to weaken, so we need to be ready for that scenario.

It’s not surprising. Decreasing rainfall in parts of the east Asian summer monsoon region has been identified in rainfall records since the 1960s, while increasing rainfall has been evident in north-western Australia since the last century, accelerating since the 1950s. Our new data suggest that further weakening of the Gulf Stream could reinforce these trends even more in the future, with consequences for both regions.

We need to put this impact into context because this region extends from China through Southeast Asia, the maritime continent, and western Indo-Pacific warm pool on the Equator, to Australia. The region is home to almost a billion people and five terrestrial Biodiversity Hotspots.

Highlights

• 150 kyr n-alkane δ2H and pollen record of monsoon strength from northern Australia.
• Coastline position strongly influenced local hydroclimate.
• Monsoon intensity broadly anti-phased with East Asian Summer Monsoon.
• Short (∼2–10 kyr) periods of dramatically increased monsoon intensity also occur.
• Short periods of increased monsoon intensity align with Heinrich events.

Abstract
Nearly two thirds of the world's population depend on monsoon rainfall, with monsoon failure and extreme precipitation affecting societies for millennia. Monsoon hydroclimate is predicted to change as the climate warms, albeit with uncertain regional trajectories. Multiple glacial-interglacial terrestrial records of east Asian monsoon variability exist, but there are no terrestrial records of equivalent length from the coupled Indo-Australian monsoon at its southern limit — Australia. We present a continuous 150,000-year lacustrine record of monsoon dynamics from the core monsoon region of northern Australia based on the proportion of dryland tree pollen in the total dryland pollen spectra and the hydrogen isotope composition of long chain n-alkanes. We show that rainfall at the site depends strongly on sea level, which changes proximity of the coast to the site by 320 km over the last glacial-interglacial cycle. Long-term trends in rainfall are broadly anti-phased with the east Asian monsoon modulated by coastal proximity. The record also contains multiple, short intervals (∼2 to < 10,000 years) of large changes in tree cover (from 5 to 95 % tree pollen over 3000 years in one instance). Changes in tree cover are frequently but not always, accompanied by synchronous large changes in the other hydroclimate proxies. While these wetter periods cannot be easily ascribed to orbitally induced changes in insolation or coastal proximity, they are correlated with most Heinrich events. This relationship implies that strong asymmetry in inter-hemispheric monsoon rainfall might be one outcome of the current weakening in the strength of the Atlantic meridional overturning circulation, through a reduction in oceanic heat transfer from the Southern to the Northern Hemisphere.

1. Introduction
The dominant feature of climate across most of the tropics and subtropics is a seasonal reversal of the prevailing winds across the Equator, resulting in a wetter summer season and a drier winter in each hemisphere. At an annual scale, the ‘global monsoon’, approximated hydrologically by the zone of maximum rainfall associated with the intertropical convergence zone, oscillates between the Northern and Southern Hemispheres (An et al., 2015; Wang et al., 2017). This oscillation is driven by the annual cycle of maximum insolation between each hemisphere (Deininger et al., 2020), leading to anti-phased summer rainy seasons in each (Eroglu et al., 2016; Deininger et al., 2020). Agriculture and ecosystems across the tropics and subtropics depend on monsoon rainfall (An et al., 2015), and so growing populations and climate change increase vulnerability to any change in monsoon dynamics (Zhang et al., 2018; Martinez-Villalobos and Neelin, 2023). Indeed, drought associated with monsoon failure, as well as monsoon-related flooding, have driven major demographic changes in prehistory (e.g., Cook et al., 2010) and the recent past (Li et al., 2011; Qian et al., 2012; Wang et al., 2015.1).

The monsoon system that affects the largest land area and human population is the east Asian summer monsoon north of the Equator, coupled by cross-equatorial airflow to the Indo-Australian summer monsoon south of the Equator (Li and Li, 2014) (Fig. 1). This region extends from China through Southeast Asia, the maritime continent and western Indo-Pacific warm pool on the Equator, to Australia. The region is home to almost a billion people and five terrestrial biodiversity hotspots (Myers et al., 2000).

Also shown are the Sunda and Sahul continental shelves, with areas landward exposed at times of lower sea level, and the major pathways for water and heat transport between the Pacific and Indian Oceans via the Indonesian throughflow. Approximate boundaries of the true and ‘pseudo’ monsoon domains and directions of wet season airflow are in yellow (Suppiah, 1992).

The Indo-Australian summer monsoon represents the dominant source of rainfall in northern Australia, although atmospheric teleconnections to other sources of global interannual climate variability, particularly El Niño-Southern Oscillation, contribute to rainfall variability (Sharmila and Hendon, 2020.2; Heidemann et al., 2023.2; Gallagher et al., 2024). The Indo-Australian summer monsoon in northern Australia also exhibits its own internal dynamics, due in approximately equal measure to local oceanic (sea surface temperature, evaporation, and wind) and terrestrial (land cover, soil moisture, evaporation, and wind) influences on rainfall (Yu and Notaro, 2020.3; Sekizawa et al., 2021.1; Heidemann et al., 2023.2; Sekizawa et al., 2023.3). While the east Asian summer monsoon is dominant due to the large, high-altitude Asian landmass, the internal dynamics of the Indo-Australian summer monsoon can also drive variability in east Asian winter monsoon rainfall in southern China, suggesting close linkages (Yu and Notaro, 2020.3; Sekizawa et al., 2021.1; Heidemann et al., 2023.2; Sekizawa et al., 2023.3).

Terrestrial speleothem oxygen isotope and pollen records (e.g., Ma et al., 2023.4; Chen et al., 2023.5) spanning one or more glacial-interglacial cycles have demonstrated periods of enhanced/(reduced) east Asian summer monsoon rainfall at times of higher/(lower) Northern Hemisphere insolation and distinct, weak monsoon intervals, some of which are coincident with Heinrich events (Cheng et al., 2009, 2016.1). However, equivalent long terrestrial records from the southern end of the Indo-Australian summer monsoon in northern Australia are conspicuously absent.

Proxy records of terrestrial runoff have been derived from marine records off north-western Australia and are correlated with east Asian summer monsoon records (Pei et al., 2021; Zhang et al., 2020.1; Sarim et al., 2023.1) (Fig. 1). However, those records are potentially confounded by the adjacent wide continental shelf that introduces an effect of sea-level change at orbital timescales on the delivery of runoff-derived sediment to the core locations. The locations are also likely affected by the large changes in land-sea distribution in the maritime continent that modify heat and mass transfer through the Indonesian throughflow upstream of the core sites (Lee et al., 2019). On land, a discontinuous speleothem time series of oxygen isotope has been generated covering the last 40 kyr (1 kyr = 1000 years) from northern Western Australia (Denniston et al., 2017.1), a location that is under the influence of the ‘pseudo’ monsoon (Suppiah, 1992; Gallagher et al., 2024) where airflow originates in the eastern Indian Ocean, rather than from equatorial regions to the north (Fig. 1).

In the arid interior of Australia, sediments from the former Woods and Gregory ‘megalakes’ (now small, ephemeral bodies of water) show that large perennial water bodies existed, dominantly during periods in Marine Isotope Stage (MIS) 3 around ∼ 50 ka ago, MIS 5 around 100 ka ago, as well as earlier (Bowler et al., 1998, 2001; Veth et al., 2009.1; Fitzsimmons et al., 2012.1). These megalakes were fed by monsoon rain falling into south-draining catchments, with drainage divides at least 300 km south of the modern north Australian coast (Fig. 1). Kati Thandi-Lake Eyre in central Southern Australia receives water from the core monsoon area (and other regions), but it also contains a record of megalake periods through MIS 5 to ∼ 116 ka ago and from 65 to 45 ka ago (Cohen et al., 2022.1).

The existence of interior megalakes, orders of magnitude larger than today's, implies past periods of higher monsoon rainfall penetrating these arid interior catchments (Wyrwoll and Valdes, 2003). Debate on the drivers of megalake-filling events has centred on the relative importance of sea level, sea surface temperatures, and Northern Hemisphere ‘push’ versus Southern Hemisphere ‘pull’ of monsoonal rain into the continental interior, as well as the role of vegetation feedbacks in augmenting moisture transfer inland (Wyrwoll and Valdes, 2003; Liu et al., 2004; Miller et al., 2005; Pitman and Hesse, 2007; Marshall and Lynch, 2008; Wyrwoll et al., 2007.1, 2012.2).

Here we present multiple, absolute-dated proxy records of sedimentological, hydroclimatic, and vegetation change over the last 150 kyr from a sediment core obtained from the core monsoon region of northern Australia, the Girraween Lagoon (Fig. 1). This record enables an assessment of the timing of variation in monsoon strength in the Indo-Australian summer monsoon domain that can be compared with records of east Asian summer monsoon strength and tropical hydroclimate. Together, this enables an assessment of the drivers of variability in the Indo-Australian summer monsoon.

The detailed sedimentary record from the Girraween Lagoon in Northern Australia, which includes evidence of Heinrich events spanning the last 150,000 years, presents a serious challenge to young Earth creationist claims. These events, triggered by massive iceberg discharges into the North Atlantic and linked to widespread climatic shifts—including monsoon disruptions in Australia—can be correlated across multiple geological archives worldwide. This implies a stable, continuous, and datable sequence of climatic change that extends far beyond the 6,000 to 10,000 years typically allowed by biblical literalists.

Creationist claims of a recent, global, catastrophic flood—often tied to the story of Noah—are also incompatible with this evidence. A flood of such scale would have scoured landscapes, disrupted or homogenised sedimentary layers, and left a very different geological signal. Instead, the sediments in Girraween Lagoon preserve a finely layered and uninterrupted record of environmental conditions, including pollen and isotopic data, spanning well over 100,000 years. Such a record simply could not survive the violent upheaval proposed by a recent global deluge.

Furthermore, the evidence of repeated, severe climatic disruptions also undermines the notion that Earth was perfectly created and "finely tuned" for life. The Heinrich events were episodes of extreme instability, during which entire regions became uninhabitable or suffered ecological collapse. This shows Earth’s climate system as dynamic and often harsh—not the static, life-friendly world one might expect from an intelligent designer. In short, the geological and climatological evidence paints a picture of an ancient, evolving Earth shaped by natural processes—one that flatly contradicts creationist dogma.

The Bronze Age Middle Eastern authors of the Bible clearly knew little of the world beyond a few days' walk from their homes in the Canaanite Hills. The world they described — and the stories they invented to fill the vast gaps in their knowledge — contained nothing unfamiliar to them. They had no way of knowing the true age of the Earth or the Universe, which they imagined to be fixed and immobile. They knew nothing of the history of living or extinct species, nor of the compelling evidence for common ancestry stretching back hundreds of thousands, even tens of millions, of years. And they were entirely unaware of the existence of other peoples living in distant lands, across vast oceans on other continents.

It should come as no surprise, then, that they got so much wrong, and that their writings omitted nearly everything science has since revealed about human origins. We now know that Homo sapiens diversified from archaic ancestors in Africa and gradually spread across the globe—migrating over land bridges now submerged by rising sea levels and eventually reaching the Americas.

Almost all of this is well-established in modern science, with the only significant uncertainty remaining around the precise timing of the first human colonisation of the Americas from Siberia. Bible literalists attempt to sidestep this discrepancy between the scientific evidence and the biblical narrative by postulating, without any supporting evidence, that the Bible was authored by an omniscient creator god. They argue that any contradiction with scientific findings must be due to mistaken interpretation, not error in the Bible. In essence, their reasoning runs: “The Bible was written by an all-knowing god because the Bible says so—therefore, any conflicting evidence must be wrong.” Instead of critically examining the claims of Bronze Age hill farmers, they demand that science must bend to fit ancient, unsubstantiated assertions.

One striking example of the scientific evidence at odds with biblical literalism is the recent confirmation that human footprints discovered at White Sands National Park, New Mexico, are 23,000 years old—some 13,000 years older than biblical literalists believe the Earth itself to be.

These footprints were discovered in 2021 and initially dated to 23,000 years ago — 10,000 years earlier than the previously accepted earliest human presence in the Americas. While this early date was controversial, a team led by Professor Vance Holliday of the University of Arizona’s School of Anthropology and Department of Geosciences has now re-evaluated the evidence and confirmed the original finding.

The team has just published their findings, open access, in Science, with an explanation in an official University of Arizona news release.

Philippine islands had technologically advanced maritime culture 35,000 years ago | News | Ateneo de Manila University

It’s shaping up to be another difficult week for creationists. Hot on the heels of news that humans were fighting and killing in northern Italy 7,000 years before the alleged ‘Creation Week’ and ‘The Fall’—events which biblical literalists claim introduced death into the world—comes fresh evidence of a sophisticated maritime culture flourishing in what is now the Philippines 18,000 years before that.

Another significant challenge for the creationist narrative is that, like the skeletal remains found in Italy, this archaeological evidence in the Philippines was not obliterated by the supposed global flood—an essential element of young Earth creationism for which there is no credible supporting evidence.

The discoveries in the Philippines were made by scientists from Ateneo de Manila University, in collaboration with international experts and institutions. Their research reveals early human migration, technological innovation, and long-distance intercultural connections dating back more than 35,000 years. The findings have been published in Archaeological Research in Asia, and are also explained in a news release from Ateneo de Manila University.

Australia’s oldest prehistoric tree frog hops 22 million years back in time

In addition to the recent discovery of early reptile tracks in Australia—dated to 350 million years before 'Creation Week'—creationists have just been given another reason to resent Australia: a 55-million-year-old fossil tree frog.

The discovery was made by three palaeontologists at the University of New South Wales in Sydney, NSW, Australia. Their findings have just been published, open access, in the Journal of Vertebrate Paleontology. It will no doubt take some of creationism's sharpest minds to devise excuses for dismissing this evidence, while continuing to cling to the childish fantasy that Earth was conjured into existence by a magical, immaterial deity just 6,000 to 10,000 years ago—along with all life, fully formed and without ancestors.

The first line of attack will likely involve misrepresenting the dating methods used, in an attempt to cast doubt on their reliability, followed by accusations that the scientists falsified their data to conform to evolutionary 'dogma' and secure publication.

What creationists must never do, however, is admit that the fossil really does date to 55 million years ago. To do so would be to concede that a literalist interpretation of the Genesis creation story is false—thereby undermining the entire premise that the Bible was written by, or inspired by, an all-knowing creator god.

Refuting Creationism - Giant Fast-Running Croccodiles In the Caribbean - 11 Million Years Before 'Creation Week'

Giant croclike carnivore fossils found in the Caribbean – Research News

Six million years before biblical literalist creationists assert Earth and all living creatures were created ex nihilo, giant long-legged, crocodile-like predators known as sebecids were hunting their prey on Caribbean islands. Remarkably, these creatures persisted long after similar species had vanished from South America, where sebecids had become apex predators following the extinction of the dinosaurs 66 million years ago.

Although sebecids went extinct on mainland South America about 11 million years ago, new evidence from Caribbean fossil records shows they survived considerably longer on islands, continuing as apex predators. This finding comes from recent research conducted by a team of palaeontologists from the Florida Museum, who have been compiling evidence over the past three decades. The team's detailed findings have now been published in the journal Proceedings of the Royal Society B. Further insights and context are available in an accompanying Florida Museum news article.

These tools, previously associated predominantly with Neanderthal populations in Europe, were discovered at the Longtan site and have been dated to approximately 50,000 to 60,000 years ago. Their presence in East Asia challenges longstanding assumptions about the technological development of early human populations in this region.

Traditionally, the Middle Paleolithic period in East Asia was thought to lack the technological innovations seen in contemporaneous European and Middle Eastern contexts. The discovery of these sophisticated tools suggests that early human groups in East Asia were engaging in complex tool-making practices similar to those of their western counterparts. This finding not only broadens our understanding of human technological evolution but also indicates a more interconnected prehistoric world than previously believed.

From a scientific perspective, such discoveries are invaluable in piecing together the mosaic of human history. However, they also pose challenges to certain interpretative frameworks, particularly those rooted in a literalist reading of religious texts. The existence of advanced tool-making practices tens of thousands of years ago stands in contrast to timelines proposed by young-Earth creationist views, which assert a much more recent origin of humanity.

In light of this, the Longtan findings serve as a compelling reminder of the importance of evidence-based inquiry in our quest to understand human origins. They underscore the dynamic and multifaceted nature of our past, inviting us to reconsider and refine our narratives in the face of new evidence.

A recurring point in this blog is that 99.9975% of Earth's history occurred before the time creationists claim the Earth was magically created out of nothing by an immaterial deity. It is strange how, despite the overwhelming evidence contradicting their viewpoint and a notable absence of credible supporting evidence, creationism endures as a belief system.

This requires either a profound lack of scientific knowledge and understanding, or extraordinary mental gymnastics, to cope with the cognitive dissonance and dismiss the abundant contrary evidence. Advocates of creationism frequently attempt to rationalise away this evidence, attributing it to errors, falsifications, or even alleging a global conspiracy within the scientific community.

Recently, another piece of evidence undermining creationist claims emerged with the publication of a study in Nature Communications. The paper documents how marine life rapidly recovered at the site of the dinosaur-killing Chicxulub asteroid impact in the Gulf of Mexico, 66 million years before creationism's mythical 'Creation Week'.

This rapid recovery was facilitated by nutrient-rich waters resulting from hydrothermal activity triggered by the asteroid collision.

Creationists might not want to hear this because they have well-rehearsed excuses for dismissing radiometric dating, but the study depended on analyzing the ratios of stable osmium isotopes in sediments at the Chicxulub impact site. This analysis is not a form of radiometric dating; rather, it involves comparing the naturally occurring ratios of these isotopes from terrestrial and meteoritic sources to trace their origin. By correlating these isotopic variations with sediment depth, researchers have inferred the contribution of meteoritic material over time.

The timing of the Chicxulub impact has been corroborated through multiple independent methods, including high-precision uranium-lead (U-Pb) dating of zircon crystals. These zircons, found in impact-related deposits, provide robust age constraints that align with the established date of the event.

Fitting the ‘missing puzzle pieces’ – research sheds light on the deep history of social change in West Papua

According to the recently published book, West New Guinea: Social, Biological, and Material Histories, by Professor Dylan Gaffney and Marlin Tolla, modern humans had arrived in what is now West Papua at least 50,000 years ago.

This is approximately 40,000 years before young Earth creationists claim their proposed deity created a small, flat Earth beneath a dome in the Middle East, along with a man formed from dust and a woman from his rib as the founding couple of the human species.

As with approximately 99.9975% of Earth's history, the vast majority of human history occurred long before the supposed ‘Creation Week’. The established record of human origins and development differs so radically from the narratives found in the Bible and Qur’an that it is remarkable anyone still considers those texts to be authoritative accounts of history or science—or even credible allegories or metaphors for anything resembling reality.

Genetic evidence further shows that, during their migrations, the ancestors of modern Papuans interbred with now-extinct archaic humans known as Denisovans. As a result, while modern Eurasians typically carry around 2% Neanderthal DNA, many populations in Island Southeast Asia and Oceania—including Austronesian peoples—carry up to 3% Denisovan DNA.

Sometimes, I almost feel sorry for creationists struggling to cling to their childish counter-factual superstition in the face of this constant deluge of contrary scientific evidence. Then I realise they are architects of their own defeat by consciously and conscientiously ignoring this contrary evidence. Remaining ignorant and so remaining wrong is a choice that they don't have to choose just to maintain the self-delusion that they are more expert than the experts.

So, I have no conscience about reporting yet another example of incontrovertible evidence of evolution on an Earth which is much older than creationists prefer to believe. It comes in the form of a reassessment of a 65-million-year-old fossil of an early mammal from the same branch of the evolutionary tree as primate, so is a distant cousin on humans.

The problem with trying to maintain a belief that Earth is between 6 and 10 thousand years old is that 99.9975% of its history occurred earlier than 10,000 years ago, so almost everything archaeologists and geologists discover will prove to be from before you believe Earth existed, which, for normal people, might just be more than a hint that Earth is considerably older than you think.

Not so for creationists however, who consider their beliefs to be sacred and unfalsifiable, so the facts must be wrong.

The traditional way is to declare that radioactive decay rates on which geological formations and archaeological artifacts are dated must have changed, sometimes by many orders of magnitude.

These same creationists will also argue in a different context that the laws of nature which govern the structure and behaviour of the Universe and everything in it are so finely tuned to support life, that they must have been set by an intelligent designer.

However one of those 'fine-tuned' parameters is the weak nuclear force that binds the protons and neutrons in the atomic nuclei and for a radioactive atom to decay means that a quantum fluctuation in the energy levels in some of these particles must exceed the weak force binding them together, so the particle is ejected. But, for radioactive decay rates to be several orders of magnitude higher, the weak nuclear force would need to be much lower, below the point at which even stable atomic nuclei form at all. This means, when they believe the universe was created along with atoms, planets and life were created, there would have been no atoms to make it all from. Life would have been impossible.

An added problem is that scientists have shown that radioactive decay rates of different elements remain absolutely constant in a range of extreme temperature and pressure conditions, so there appears to be no support whatsoever for the declaration that decay rates have changed by several orders of magnitude so that an age of 10,000 year or less just happens to look like 300 million years or whatever finding is being waved aside.

If there were any merit in the creationist claim of a fine-tuned Universe, then it has been fine-tuned to make it look 14 billion years old, Earth to look nearly 4 billion years old and living organisms to have been on it for most of that time.

With that in mind then, researchers have just announced that they have found evidence of the presence of hominins in Eurasia 2 million years ago, which pushes back the earliest evidence of hominin presence outside Africa by at least 150,000 years to a time considerably earlier than Homo sapiens first appear in the fossil record - supporting the theory that the earliest migration into Eurasia was by an archaic hominin such as H. erectus.

Fossils and fires: insights into early modern human activity in the jungles of Southeast Asia – News

At the same time that creationists believe their small god was making a universe consisting of a small flat planet with a dome over it in the Middle East, then magicking a man a d a woman without ancestors, real humans were living in the jungles of Southeast Asia and making camp fires, around which they were probably making up origin myths just like the Middle Eastern Bronze Age pastoralists did. The difference was, their myths didn't get written down and included in a book declared to be the inerrant word of a magic man in the sky, so they aren't available to fool gullible people with today.

Instead, they left tangible records of their activities that scientists are now discovering and dating to between 52,000 and 10,000 years ago; records moreover that if the campfire tales of the Middle East had any truth in them would have been swept away and destroyed or covered with a deep layer of silt containing the bodies and remains of the animals and plants destroyed in the mythical global genocidal flood inflicted on the planet by an irascible magic despot.

Ironically, the human remains found buried in sediment in a cave floor were probably washed into the cave by a local flood, so all the other fossils at that location are also of local species, not the world-wide jumble that a global flood would have produced.

Tell me about the prehistoric history of the humans who occupied the Tam Pà Ling cave in Laos, please. The Tam Pà Ling cave, located in northern Laos, has yielded some of the most significant prehistoric human remains in Southeast Asia, providing key insights into the early human migrations in the region. The cave, whose name means "Cave of the Monkeys," sits at around 1,170 meters above sea level in the Annamite Mountains, making it an ideal site for shelter during prehistoric times.

Key Findings and Human Occupation
The site became famous when researchers unearthed several human fossils, including a cranium and jawbones, that have been radiocarbon dated between 46,000 and 63,000 years ago. These discoveries suggest that anatomically modern humans (*Homo sapiens*) were present in Southeast Asia much earlier than previously believed. The remains from Tam Pà Ling are considered some of the oldest evidence of modern humans in mainland Asia.

Significance in Human Migration
The fossils found in Tam Pà Ling have played an essential role in understanding the "Out of Africa" migration, where *Homo sapiens* spread from Africa to the rest of the world. The cave’s location, relatively close to the Mekong River, is thought to have been part of a corridor that early humans used as they moved from Africa through the Middle East, into South Asia, and ultimately into Southeast Asia and Australia.

The discovery of such early modern human remains in Laos supports the theory that early humans reached Southeast Asia via inland routes, rather than following only coastal paths. This inland route theory aligns with the ecological diversity of the region, which would have provided rich resources for early hunter-gatherer groups.

Anatomical Evidence
The fossils found in Tam Pà Ling are distinctly modern in their features. The skulls exhibit traits that are fully consistent with *Homo sapiens*, such as a high forehead, rounded braincase, and small, flat faces. However, some subtle characteristics, like thicker bones and robustness, indicate potential regional adaptations or the influence of archaic hominins like *Homo erectus* or *Denisovans*, both of whom were known to have existed in the broader region.

Cultural Context
No significant cultural artifacts, such as tools or other evidence of complex human behavior, have been found alongside the fossils in Tam Pà Ling, which leaves some aspects of the lives of these early inhabitants uncertain. Nonetheless, their presence in the cave hints at how early humans adapted to diverse environments—ranging from highland caves like Tam Pà Ling to coastal areas.

Importance in the Global Human Evolution Story
The discovery of these early human remains in Tam Pà Ling has contributed to the global conversation on human evolution. It suggests that *Homo sapiens* coexisted with archaic hominins in Asia longer than once thought. It also challenges the idea that humans primarily spread through coastal routes, indicating that Southeast Asia was likely populated by multiple waves of migration, using both coastal and inland routes.

The Tam Pà Ling site remains an important location for understanding the complexity of early human migration and the spread of *Homo sapiens* across the globe.

The cave is the Tam Pà Ling cave, located in northern Laos where Laotian, French, American and Australian archaeologists have been working for some 14 years to unearth the secrets contained in it.

Now a new study, led by PhD candidate Vito Hernandez and Associate Professor Mike Morley from the College of Humanities, Arts and Social Sciences at Flinders University, SA, Australia, has reconstructed the ground conditions inside the cave between 52,000 and 10,000 years ago. They have just published their findings in Quaternary Science Reviews and announced them in a Flinders University news release:

Excavation of the Tam Pà Ling cave

Now a new study, led by PhD candidate Vito Hernandez and Associate Professor Mike Morley from the College of Humanities, Arts and Social Sciences, has reconstructed the ground conditions in the cave between 52,000 and 10,000 years ago.

Using a technique known as microstratigraphy at the Flinders Microarchaeology Laboratory, we were able to reconstruct the cave conditions in the past and identify traces of human activities in and around Tam Pà Ling. This also helped us to determine the precise circumstances by which some of the earliest modern human fossils found in Southeast Asia were deposited deep inside.

Microstratigraphy allows scientists to study dirt in its smallest detail, enabling them to observe structures and features that preserve information about past environments and even traces of human and animal activity that may have been overlooked during the excavation process due to their minuscule size.

The human fossils discovered at Tam Pà Ling were deposited in the cave between 86,000–30,000 years ago but until now, researchers had not conducted a detailed analysis of the sediments surrounding these fossils to gain an understanding of how they were deposited in the cave or the environmental conditions at the time.

Published in Quaternary Science Reviews, the findings reveal conditions in the cave fluctuated dramatically, going from a temperate climate with frequent wet ground conditions to becoming seasonally dry.

This change in environment influenced the cave’s interior topography and would have impacted how sediments, including human fossils, were deposited within the cave. How early Homo sapiens came to be buried deep within the cave has long been debated, but our sediment analysis indicates that the fossils were washed into the cave as loose sediments and debris accumulating over time, likely carried by water from surrounding hillsides during periods of heavy rainfall.

The team also identified preserved micro-traces of charcoal and ash in the cave sediments, suggesting that either forest fires occurred in the region during the drier periods, or that humans visiting the cave may have used fire, either in the cave or near the entrance.

This research has allowed our team to develop unprecedented insights into the dynamics of our ancestors as they dispersed through the ever-changing forest covers of Southeast Asia, and during periods of variable regional climate instability.

Late Pleistocene–Holocene (52–10 ka) microstratigraphy, fossil taphonomy and depositional environments from Tam Pa Ling cave (northeastern Laos) Quaternary Science Reviews (2024) 108982. DOI: 10.1016/j.quascirev.2024.108982

Highlights

• Late Pleistocene-Holocene cave sediments from Tam Pà Ling, northeastern Laos, were geoarchaeologically investigated.
• Microstratigraphic analyses were employed.
• Ground and ambient conditions vary in the cave ∼52–10 ka.

Abstract
Fossil evidence for some of the earliest Homo sapiens presence in mainland Southeast Asia have been recovered from Tam Pà Ling (TPL) cave, northeastern Laos. Taphonomic indicators suggest that these human fossils washed into TPL via gradual colluviation at varying times between MIS 5–3, yet no attempt has been made to situate them within the depositional environments of the cave within these periods. This has precluded a deeper appreciation of their presence there and in the surrounding landscape. In this first microstratigraphic study of TPL, we primarily use sediment micromorphology to reconstruct the depositional environments of the cave, relate these environments with the taphonomic history of the human fossils recovered from the upper 4 m of the excavated sequence, and explore how the sediments can better explain the presence of these humans in the area during MIS 3–1 (52–10 ka). Our results demonstrate changes in local ambient conditions from being temperate to arid, with ground conditions often wet during MIS 3 and becoming increasingly seasonal (wet-dry) during MIS 2–1. The changing cave conditions impacted its interior topography and influenced the way sediments (and fossils) were deposited. Preserved combustion biproducts identified in the sediments suggest two possible scenarios, one where small forest fires may have occurred during periods of regional aridity and/or another where humans visited the cave.

1. Introduction
The excavations in Tam Pà Ling (Cave of Monkeys), northeastern Laos (Fig. 1A), have unearthed a fossil assemblage of Homo sapiens that is unique for the study of Late Pleistocene human evolution in Southeast Asia (SEA) (Demeter et al., 2012; Demeter et al., 2015; Demeter et al., 2017; Shackelford et al., 2018; Freidline et al., 2023). The fossil assemblage is formed of a partial cranium (TPL1), two mandibles (TPL2, TPL3), a partial rib (TPL4), a proximal pedal phalanx (TPL5), a partial frontal (TPL6), and a tibial fragment (TPL7), all excavated from a trench situated deep inside the cave. Although disarticulated, the fossils otherwise display minimal evidence of remobilisation or physical abrasion, a rare occurrence from the region (Lee and Hudock, 2021; Sawafuji et al., 2024). As such, the fossils have helped demonstrate the major morphological variations that existed between the different populations of Homo sapiens in SEA during the Late Pleistocene (Demeter et al., 2017), consequently making Tam Pà Ling (TPL) a key site for the study of the evolution and dispersal of our species in the Far East (Matsumura et al., 2019; Demeter and Bae, 2020; Hublin, 2021.1; McAllister et al., 2022; Sawafuji et al., 2024).

The TPL fossils represent some of the earliest evidence for Homo sapiens in continental SEA, deposited in the cave at different times between Marine Isotope Stage (MIS) 5b and MIS 3 (∼87–30 ka) (Freidline et al., 2023). Although some of the fossils have been directly dated via uranium–thorium methods, their dates are reported only as minimum age estimates (Demeter et al., 2012, 2015). This is largely due to the unaccounted profiles of uranium from the sampled deposits, noting that tropical environments hold the potential of enhancing heterogeneous distribution of uranium in bones that are chemically weathered in situ. Hence, the modelled depositional ages (2σ) of the containing sediment matrix are preferred when referring to the age of the fossils, with the oldest returned age estimate being ∼86 ka, supporting a much earlier dispersal of Homo sapiens into SEA than previously known. Details of the modelled depositional chronology of TPL are published in Freidline et al. (2023). Whereas palaeoenvironmental reconstructions of the landscape surrounding TPL have provided some context to understand the early dispersal of Homo sapiens in SEA (Milano et al., 2018.1; Bourgon et al., 2021.2; McAllister-Hayward et al., 2024.1), there is still very little understanding of their presence at the site and in the local catchment, other than the occurrence of the fossils. This largely precludes the development of more detailed scenarios for the early Homo sapiens settlement of Asia (Dennell, 2017.1) and achieving a better understanding of their adaptations to environmental changes in tropical landscapes, which are argued to play an important role in human evolution and dispersals in the deep past (Scerri et al., 2022.1 and references therein). In SEA, such knowledge remains elusive due to the limited evidence from the Pleistocene archaeological record and the current resolution of ages that frame the presence of humans at many of the studied sites.

While the ages of the fossils from TPL are well-constrained, the absence of artefacts or occupation surfaces found to date suggests that humans did not intensively occupy the cave during the Late Pleistocene. However, evidence of human presence and occupation at neighbouring sites spanning the Middle Pleistocene to Late Holocene (Demeter et al., 2009; Patole-Edoumba, 2015.1; Bacon et al., 2021.3; Demeter et al., 2022.2, Fig. 1B), and the presence of the fossils from TPL, suggest that humans may have at least visited sporadically or used the cave in the past, even briefly. If so, then traces of their activities from the entrance or even inside might still be preserved, although likely in small quantities, probably degraded, diagenetically altered, or buried beneath limestone slabs.

The research at TPL has simultaneously highlighted the scientific challenges of understanding archaeological site formation processes in the hot and humid tropics (Morley and Goldberg, 2017.2 and references therein), and the need to better understand geomorphological processes that affect the interpretation and dating of fossils from cave sites (Liu et al., 2015.2; Westaway et al., 2017.3; Yao et al., 2020.1). These challenges are made more difficult by the erratic preservation of organic materials in tropical cave environments (Louys et al., 2017.4 and references therein; Smith et al., 2020.2 and references therein), and therefore demand the systematic evaluation of the stratigraphy of a site with the potential to yield bioarchaeological data (e.g., aDNA, proteins) that can inform about humans and their environments in the past (Massilani et al., 2022.3; Morley et al., 2023.1; Aldeias and Stahlschmidt, 2024.2). It is for these reasons that there is a need to better understand the stratigraphy of TPL at various spatial scales (vertical and horizontal) and at finer resolution, with research from other sites in SEA suggesting a geoarchaeology-focused approach to achieve this (O'Connor et al., 2010; Morley, 2017.5).

Sediment micromorphology (microstratigraphy) is one method employed in geoarchaeological research that can help to better understand the geomorphological and site formation processes governing TPL. Research employing this method to study the critical sites for understanding early human evolution and dispersals in SEA show that microstratigraphy can provide a more nuanced picture of local environments in the past, help to reveal more about human adaptations to the different environmental conditions that existed, and temporally resolve the presence of humans on-site and in the immediate catchment (Stephens et al., 2005, 2017.6; Lewis, 2007; Brasseur et al., 2015.3; Mijares, 2017.7; Morley et al., 2017.8; McAdams et al., 2020.3; Anderson et al., 2024.3; Shipton et al., 2024.4). With these in mind, a program of microstratigraphic analysis at TPL was initiated to gain further insights into the history of the site and the taphonomy of the Homo sapiens fossils recovered from there.

To improve the understanding of the history of the site and taphonomy of Homo sapiens fossils recovered from TPL we link the results of the microstratigraphic analysis with loss-on-ignition (LOI) and magnetic susceptibility (χ) analysis of sediments. Both methods provide quick to obtain and accurate determinations of geochemical characteristics that can complement the interpretation of the microstratigraphic record (Stoops, 1978; Macphail and Goldberg, 2017.9). LOI, for instance, has complemented microstratigraphic analysis of archaeological cave sites in Malaysia, northern Vietnam and Thailand, resulting in a clearer understanding of the depositional environments that existed in these caves in the past (Hunt et al., 2007.1; Stephens et al., 2016; McAdams et al., 2020.3; Saminpanya and Denkitkul, 2020.4). While χ has been used at TPL to infer moisture availability that helped to reconstruct the vegetation surrounding the cave during the Late Pleistocene (Milano et al., 2018.1) and allowed insights into the timing of sediment delivery into the cave during periods of strengthened monsoons (Freidline et al., 2023). By linking the results of these analyses with that of the microstratigraphy, it is hoped that a clearer understanding of site formation and better explanation of the presence of humans at TPL is achieved.

Here, we present the results of the program to analyse the microstratigraphy, LOI and χ of sediments in TPL. Our geoarchaeological work aims to prove the efficacy of a microstratigraphic approach to understanding the important stratigraphy of the site by reconstructing its ground conditions, clarifying the taphonomic history of the fossils related to the depositional history of the cave, and exploring the potential archaeology within its sediments. By doing so, we try to resolve how past conditions in TPL (sediment, cave, and catchment) affect the interpretation of human presence at the site and explore how this information changes the narrative of Late Pleistocene human evolution and dispersals in the Far East. We focus the analyses on the upper 4 m Late Pleistocene–Holocene sediment sequence exposed in the 7 m-deep excavation inside the cave. This upper sequence was securely dated to between 46 ± 6 ka and 13 ± 3 ka (Freidline et al., 2023) and was where the human fossils TPL1, 2 and 5 were recovered (Demeter et al., 2012, Demeter et al., 2015, Demeter et al., 2017).

The refutation of creationism continues unabated. Not only were there people living in South East Asia tens of thousands of years before creationists think Earth was created by magic, but the remains proving it were washed into the cave by a local flood, which, had it been anything resembling creationism's favourite genocidal flood, would also have washed in non-local debris. And that simply never happened, then or later.

And, to make it doubly difficult for creationists to explain without the usual lies and misrepresentations of the dating methods used, the authors have allowed for possible errors by using the minimum ages of the fossils. In other words, if creationists are right about errors in the dating methods, these fossils are even older than creationists dogma says they should be.

And so creationism staggers on under the load of yet more evidence that it is just a childish fairytale.

For another o todays casual and incidental refutations of creationism, we have news about the climate in Western Australia, 90,000 years before creationists little god magicked up a small flat planet with a dome over it, according to the book of Bronze Age creation myths that creationists have mistaken for a science textbook.

Of course, when everything else about Earth's history occurred in the 99.9975% of its history that occurred before the mythical 'Creation Week', this will come as no surprise to anyone who is not functionally illiterate with the thinking ability of a slow 9year-old.
