Creationism Refuted - Rappid Diversification Linked To Rapid Environmental Changes
Most known species evolved during 'explosions' of diversity, shows first analysis across 'tree of life'
A new study in Frontiers in Ecology & Evolution delivers a striking confirmation of evolutionary theory while dealing another blow to creationist claims. Researchers John J. Wiens (University of Arizona) and Daniel S. Moen (University of California, Riverside) show that the vast majority of Earth’s species richness stems from a handful of lineages that underwent explosive bursts of diversification — precisely what evolutionary theory predicts.
Analysing enormous datasets covering more than 2 million described species across multiple taxonomic levels, the team found that "over 80% of all known biodiversity is packed into the clades with the fastest diversification rates". This pattern holds true for animals, plants, insects, vertebrates, and even across kingdoms, showing that biodiversity is not spread evenly but arises overwhelmingly from rapid radiations and occurs at all taxonomic levels. The message is clear: most of life’s diversity comes from bursts of speciation linked to ecological opportunity and innovation, not from slow, uniform accumulation over time. The results reveal a universal pattern across the tree of life, confirming that natural selection acting on changing environments and new niches drives the extraordinary richness we see today. For creationists, this is more bad news. Their model of static “kinds” appearing fully formed cannot explain why biodiversity clusters so strongly in rapidly radiating groups, or why it forms the nested hierarchies that evolution predicts. The evidence instead shows life as a continuous, dynamic process of descent with modification from common ancestors—exactly as Darwin envisaged, and the exact opposite of “special creation.”

Refuting Creationism - The Difference Between The Bible And Reality - ESA's Picture Of The Week
Noteworthy nearby spiral | ESA/Hubble
Everywhere science looks, it exposes the widening gulf between the way the Bronze Age authors of the Bible imagined their tiny fragment of the cosmos and the reality we now know. Astronomy, no less than biology, geology, or palaeontology, makes clear just how limited and naïve that worldview was.
Today’s reminder of that contrast comes from the European Space Agency’s “Picture of the Week”: the so-called “nearby” spiral galaxy NGC 2835, lying a mere 35 million light-years away in the constellation Hydra, the Water Snake. In other words, the light now reaching our eyes began its journey 35 million years before the Bible’s writers imagined the universe springing into existence at the command of a magic incantation — יְהִי אוֹר (yehi or! — “Let there be light”), curiously spoken in a language there was no-one else alive to understand.
And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. And God set them in the firmament of the heaven to give light upon the earth, And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.(Genesis 1.16-18)
A previous Hubble image of this galaxy was released in 2020, and the NASA/ESA/CSA James Webb Space Telescope turned its gaze toward NGC 2835 in recent years as well. Do you see anything different between today’s image of NGC 2835 and the previously released versions? Overall, NGC 2835 looks quite similar in all of these images, with spiral arms dotted with young blue stars sweeping around an oval-shaped centre, where older stars reside.
This image differs from previously released images because it incorporates new data from Hubble that captures a specific wavelength of red light called H-alpha. The regions that are bright in H-alpha emission can be seen along NGC 2835’s spiral arms, where dozens of bright pink nebulae appear like flowers in bloom. Astronomers are interested in H-alpha light because it signals the presence of several different types of nebulae that arise during different stages of a star’s life. Newborn massive stars create nebulae called H II regions that are particularly brilliant sources of H-alpha light, while dying stars can leave behind supernova remnants or planetary nebulae that can also be identified by their H-alpha emission.
By using Hubble’s sensitive instruments to survey 19 nearby galaxies, researchers aim to identify more than 50 000 nebulae. These observations will help to explain how stars affect their birth neighbourhoods through intense starlight and winds.
[Image Description: A spiral galaxy seen face-on. Its centre is a bright glowing yellow. The galaxy’s spiral arms contain sparkling blue stars, pink spots of star formation, and dark threads of dust that follow the arms.]
NGC 2835.Imagine being so ignorant and/or brain-washed as to believe that description in the Bible was the best available description of the universe, far surpassing for accuracy and reliability anything that science can reveal. And yet, there are adults alive today, with access to free information on a scale of which our forebears could only dream, whose understanding of the universe and how it works is no better than that of a Bronze Age pastoralist from the ignorant and fearful infancy of our species.
Basic Facts
- Type: Barred spiral galaxy (classification: SAB(rs)c).
- Constellation: Hydra (the Water Snake).
- Distance: Approximately 35 million light-years from Earth.
- Size: Roughly 65,000 light-years in diameter (about two-thirds the size of the Milky Way).
- Apparent magnitude: About 10.3 – faint, but visible in medium-sized amateur telescopes.
- Discovery: Found by William Herschel in 1785.
Structure & Appearance
- Spiral arms: Loosely wound, full of star-forming regions and young blue stars.
- Bar: Weakly barred, meaning it has a small central bar feature that helps channel gas inward.
- Core: Contains a supermassive black hole, though smaller than the one in the Milky Way. Estimates put it at around 3–10 million solar masses.
- Dust lanes: Dark filaments of interstellar dust wind through the spiral arms, silhouetted against the starlight.
- Star formation: Active in the outer arms, with pinkish H II regions where new stars are being born.
Observations
- Amateur astronomy: At magnitude 10.3, it’s not visible to the naked eye, but can be seen with a small-to-medium telescope under dark skies. It appears as a faint oval haze with a brighter core.
- Professional imaging: The Hubble Space Telescope has taken a detailed image of NGC 2835, showing the spiral arms rich in blue stars and reddish star-forming regions.
Scientific Interest
- NGC 2835 is often studied as a nearby example of a typical spiral galaxy.
- Its moderate distance and orientation (almost face-on) make it ideal for examining:
- Stellar population gradients (how star ages vary from core to arms).
- Gas and dust distribution in spirals.
- Black hole scaling relations (comparing the mass of central black holes to properties of host galaxies).
This wilful ignorance can only be the result of a pathological mind virus.

Refuting Creationism - Just How Wrong Could The Bible's Authors Be?
This article is best read on a laptop, desktop, or tablet
'Most massive black hole ever discovered' is detected | The Royal Astronomical Society
The authors of Genesis got so much so badly wrong that it’s difficult to find anything they got right — but the hardest place to find even a sliver of accuracy is their description of the universe. With their naïve attempt to explain the existence of different kinds of animals, they at least recognised that there were different species. Their notion of magical creation out of nothing, without ancestry, was of course laughably wrong, but at least they knew there were distinct organisms requiring explanation.
By contrast, in their picture of the cosmos — centred on a small, flat world with a solid dome (the “firmament”) over it—about the only things they got right were the existence of Earth, the Sun and Moon, and “the stars”. Everything else was subsumed into that one word: “stars”, a bucket that included the visible planets, distant suns, and entire galaxies, all imagined as lights fixed to the dome, with the Sun and Moon set within it.
In short, almost everything in that description is wrong—not just what things are, but where they are. They spoke about light, but knew nothing of its nature. That they noticed that light comes from luminous bodies is probably the only thing they got right.
Black Holes: Nature’s Most Extreme Objects. A black hole is a region of spacetime where gravity is so intense that nothing—not even light—can escape. They form when a massive star collapses under its own gravity or through the merger of smaller black holes.And of course, they could have known nothing about black holes, or about the relationship between mass and gravity that explains them and governs the motions of the “stars”.
Event Horizon
The vent horizon is the “point of no return” surrounding a black hole. Once anything crosses it, escape is impossible. From outside, the event horizon appears as a dark sphere; it’s not a physical surface but a boundary defined by relativity.
Singularity
At the very centre, according to general relativity, lies a singularity — a point where density and spacetime curvature become infinite, and the known laws of physics break down. In reality, quantum effects are expected to smooth out this infinity, but a complete theory of quantum gravity is needed to describe it properly.
Relativity vs Quantum Physics
Black holes are unique because they combine two regimes of physics:
- Einstein’s general relativity describes how they warp spacetime.
- Quantum mechanics governs the behaviour of particles and energy at extremely small scales.
The crossover between these domains lies deep inside the black hole, in a region near the singularity sometimes called the quantum gravity zone, where spacetime curvature reaches the Planck scale and neither theory works alone. This is not the event horizon, as is sometimes said; the event horizon is still very much part of the Relativity domain.
The Firewall Hypothesis
Stephen Hawking and others noted a paradox: quantum theory predicts that information cannot be destroyed, yet anything crossing an event horizon seems lost forever. One proposed resolution is the firewall hypothesis: instead of passing smoothly through, anything hitting the horizon would be incinerated by a burst of high-energy radiation. This “firewall” would break relativity’s expectation that crossing the horizon is uneventful (for a large black hole) but would preserve quantum theory’s rules.
Open Questions
- Does the singularity really exist, or is it replaced by something else in a quantum theory of gravity?
- Do firewalls exist, or is there a different resolution to the black hole information paradox?
- Can Hawking radiation—tiny energy leaks predicted by quantum field theory—eventually cause black holes to evaporate completely?
Black holes remain one of physics’ most powerful testing grounds, where the deepest laws of nature are pushed to their limits.
A point I’ve made here before — worth making again — is that we can be certain the Bible was not written by a creator god by seeing how much of it is flatly wrong. Much of it can’t even be rescued as meaningful metaphor or allegory—the standard apologetic for obvious falsehoods. It is simply, unarguably, and unambiguously wrong on multiple levels.
If a creator god had written it as a vital message to humankind, why did it not include anything unknown at the time in unmistakable terms, as proof of divine authorship and omniscience? Why, for example, did it not tell us about atoms, germs, or galaxies; that Earth is an oblate spheroid orbiting the Sun along with other planets; or explain the relationship between mass and gravity and why black holes exist?
Why not? Because the authors of the Bible were ignorant of these things. They were not creator gods, but ancient Near Eastern writers doing their best to invent plausible narratives within their cultural preconceptions — of a spirit-filled world that ran on magic — when everything they knew lay within a few days’ walk of home in the hills of Canaan.
So, compare their description of the universe as they imagined it with what science now shows us: in this case, an ultramassive black hole revealed by how its gravity bends light from a background galaxy into an “Einstein ring”, a phenomenon predicted by Einstein’s general theory of relativity.
The description comes from the Royal Astronomical Society news release and the open-access paper in Monthly Notices of the Royal Astronomical Society.
First, let's see how the Bible's author described the entire universe as they saw it without the benefit of scientific instruments or theoretical physics:

And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. And God set them in the firmament of the heaven to give light upon the earth, And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.(Genesis 1.16-18)
Now compare that to this image of a tiny fragment of it that astronomers at the Royal Astronomical Society have just released. It shows the gravity lensing effect and the resulting Einstein ring. Ber in mind that this is a tiny fragment of the universe that would be entirely hidden by a grain of rice held between the thumb and forefinger of your outstretched arm. There is absolutely nothing to compare it with in the Bible, obviously.
'Most massive black hole ever discovered' is detected
Astronomers have discovered potentially the most massive black hole ever detected.
The cosmic behemoth is close to the theoretical upper limit of what is possible in the universe and is 10,000 times heavier than the black hole at the centre of our own Milky Way galaxy.
It exists in one of the most massive galaxies ever observed – the Cosmic Horseshoe – which is so big it distorts spacetime and warps the passing light of a background galaxy into a giant horseshoe-shaped Einstein ring.

Such is the enormousness of the ultramassive black hole’s size, it equates to 36 billion solar masses, according to a new paper published today in Monthly Notices of the Royal Astronomical Society.
It is thought that every galaxy in the universe has a supermassive black hole at its centre and that bigger galaxies host bigger ones, known as ultramassive black holes.
This is amongst the top 10 most massive black holes ever discovered, and quite possibly the most massive. Most of the other black hole mass measurements are indirect and have quite large uncertainties, so we really don't know for sure which is biggest. However, we’ve got much more certainty about the mass of this black hole thanks to our new method.

Researchers detected the Cosmic Horseshoe black hole using a combination of gravitational lensing and stellar kinematics (the study of the motion of stars within galaxies and the speed and way they move around black holes).
The latter is seen as the gold standard for measuring black hole masses, but doesn't really work outside of the very nearby universe because galaxies appear too small on the sky to resolve the region where a supermassive or ultramassive black hole lies.
[Adding in gravitational lensing helped the team] push much further out into the universe. We detected the effect of the black hole in two ways – it is altering the path that light takes as it travels past the black hole and it is causing the stars in the inner regions of its host galaxy to move extremely quickly (almost 400 km/s). By combining these two measurements we can be completely confident that the black hole is real.
Professor Thomas Collett.
This discovery was made for a 'dormant' black hole – one that isn’t actively accreting material at the time of observation. Its detection relied purely on its immense gravitational pull and the effect it has on its surroundings. What is particularly exciting is that this method allows us to detect and measure the mass of these hidden ultramassive black holes across the universe, even when they are completely silent.

The Cosmic Horseshoe black hole is located a long way away from Earth, at a distance of some 5 billion light-years.

Typically, for such remote systems, black hole mass measurements are only possible when the black hole is active. But those accretion-based estimates often come with significant uncertainties. Our approach, combining strong lensing with stellar dynamics, offers a more direct and robust measurement, even for these distant systems.
Carlos Melo-Carneiro.
The discovery is significant because it will help astronomers understand the connection between supermassive black holes and their host galaxies.
We think the size of both is intimately linked, because when galaxies grow they can funnel matter down onto the central black hole. Some of this matter grows the black hole but lots of it shines away in an incredibly bright source called a quasar. These quasars dump huge amounts of energy into their host galaxies, which stops gas clouds condensing into new stars.
Professor Thomas Collett.
Our own galaxy, the Milky Way, hosts a 4 million solar mass black hole. Currently it's not growing fast enough to blast out energy as a quasar but we know it has done in the past, and it may will do again in the future.
The Andromeda Galaxy and our Milky Way are moving together and are expected to merge in about 4.5 billion years, which is the most likely time for our supermassive black hole to become a quasar once again, the researchers say.
An interesting feature of the Cosmic Horseshoe system is that the host galaxy is a so-called fossil group.
Fossil groups are the end state of the most massive gravitationally bound structures in the universe, arising when they have collapsed down to a single extremely massive galaxy, with no bright companions.
It is likely that all of the supermassive black holes that were originally in the companion galaxies have also now merged to form the ultramassive black hole that we have detected. So we're seeing the end state of galaxy formation and the end state of black hole formation.
Professor Thomas Collett.
The discovery of the Cosmic Horseshoe black hole was somewhat of a serendipitous discovery. It came about as the researchers were studying the galaxy’s dark matter distribution in an attempt to learn more about the mysterious hypothetical substance.
Now that they’ve realised their new method works for black holes, they hope to use data from the European Space Agency’s Euclid space telescope to detect more supermassive black holes and their hosts to help understand how black holes stop galaxies forming stars.

ABSTRACTThe discovery and analysis of black holes, and phenomena such as Einstein rings, would have been utterly incomprehensible to the authors of the Bible. These were people with no concept of galaxies, the vastness of the universe, or even that Earth is a sphere orbiting the Sun. Their worldview was of a flat Earth covered by a solid dome, with the Sun, Moon, and “stars” fixed to it. The very idea of light being bent by gravity, or of objects so massive that even light cannot escape, would have been as far beyond their imagination as quantum mechanics itself.
Supermassive black holes (SMBHs) are found at the centre of every massive galaxy, with their masses tightly connected to their host galaxies through a co-evolution over cosmic time. For massive ellipticals, the SMBH mass (\(\small M_\text{BH}\)) strongly correlates with the host central stellar velocity dispersion (\(\sigma_e\)), via the relation. However, SMBH mass measurements have traditionally relied on central stellar dynamics in nearby galaxies (\(\small z \lt 0.1\)), limiting our ability to explore the SMBHs across cosmic time. In this work, we present a self-consistent analysis combining 2D stellar dynamics and lens modelling of the Cosmic Horseshoe gravitational lens system (\(z_l = 0.44\)), one of the most massive lens galaxies ever observed. Using MUSE integral-field spectroscopy and high-resolution Hubble Space Telescope imaging, we simultaneously model the radial arc – sensible to the inner mass structure – with host stellar kinematics to constrain the galaxy’s central mass distribution and SMBH mass. Bayesian model comparison yields a \(\small 5\sigma\) detection of an ultramassive black hole with \(\small \log _{10}(M_\text{BH}/{\rm M}_{\odot }) = 10.56^{+0.07}_{-0.08} \pm (0.12)^\text{sys}\), consistent across various systematic tests. Our findings place the Cosmic Horseshoe \(\small 1.5\sigma\) above the \(\small M_\text{BH}-\sigma_e\) relation, supporting an emerging trend observed in brightest cluster galaxies and other massive galaxies, which suggests a steeper \(\small M_\text{BH}-\sigma_e\) relationship at the highest masses, potentially driven by a different co-evolution of SMBHs and their host galaxies. Future surveys will uncover more radial arcs, enabling the detection of SMBHs over a broader redshift and mass range. These discoveries will further refine our understanding of the \(\small M_\text{BH}-\sigma_e\) relation and its evolution across cosmic time.
1 INTRODUCTION
Most massive galaxies are believed to host a supermassive black hole (SMBH) at their centre. More importantly, host galaxies and their SMBHs exhibit clear scaling relations, pointing to a co-evolution between the galaxy and the SMBH (Kormendy & Ho 2013). The SMBH mass (\(\small M_{\text{BH}\)) has been shown to correlate with various galaxy properties, such as the bulge luminosity (e.g. Magorrian et al. 1998; Marconi & Hunt 2003; Gültekin et al. 2009), stellar bulge mass (e.g. Laor 2001; McLure & Dunlop 2002), dark matter (DM) halo mass (e.g. Marasco et al. 2021; Powell et al. 2022), number of host’s globular clusters (e.g. Burkert & Tremaine 2010; Harris, Poole & Harris 2014), and stellar velocity dispersion (e.g. Gebhardt et al. 2000; Beifiori et al. 2009.1). Notably, the \(\small M_\text{BH}-\sigma_e\) relation, which links SMBH mass to the effective stellar velocity dispersion of the host (\(\small \sigma_e\)), remains tight across various morphological types and SMBH masses (van den Bosch 2016). None the less, when SMBHs accrete mass from their neighbourhoods, they can act as active galactic nuclei (AGNs), injecting energy in the surrounding gas in a form of feedback. This feedback can be either positive, triggering star formation (Ishibashi & Fabian 2012; Silk 2013.1; Riffel et al. 2024), or negative quenching galaxy growth (e.g. Hopkins et al. 2006; Dubois et al. 2013.2; Costa-Souza et al. 2024.1).
It is expected that the most massive galaxies in the Universe, such as brightest cluster galaxies (BCGs), host the most massive SMBHs. Indeed, so-called ultramassive black holes (UMBHs; \(\small M_\text{BH} \ge 10^{10}M_\odot\)) have been found in such systems (e.g. Hlavacek-Larrondo et al. 2012.1). Most of these UMBHs have been measured through spatially resolved dynamical modelling of stars and/or gas. For instance, the UMBH in Holm 15A at \(\small z=0.055\) \(\small M_\text{BH} = (4.0 \pm 0.80) \times 10^{10}M_\odot\) (; Mehrgan et al. 2019) and the UMBH in NGC 4889 at \(\small z = 0.021\) (\(\small M_\text{BH} = (2.1 \pm 1.6) \times 10^{10}M_\odot\); McConnell et al. 2012.2) were both determined using stellar dynamical modelling. However, despite the success of this technique in yielding hundreds of SMBH mass measurements, the requirement for high-quality spatially resolved spectroscopy poses significant challenges for studies at increasing redshift (see e.g. Kormendy & Ho 2013, Suplemental Material S1).
None the less, the significance of these UMBHs lies in the fact that many of them deviate from the standard linear \(\small M_\text{BH} - \sigma_e\) relation (e.g. Kormendy & Ho 2013; den Bosch 2016). This suggests either a distinct evolutionary mechanism governing the growth of the largest galaxies and their SMBHs (McConnell et al. 2011), leading to a significantly steeper relation (Bogdán et al. 2018), or a potential decoupling between the SMBH and host galaxy co-evolution. Populating the high-mass end of the \(\small M_\text{BH} - \sigma_e\) relation, particularly through direct \(\small M_\text{BH}\) measurements, could help resolve this ongoing puzzle.
Recently, Nightingale et al. (2023), by modelling the gravitationally lensed radial image near the the Abell 1201 BCG (\(\small z=0.169\)), was able to measure the mass of its dormant SMBH as \(\small M_\text{BH} = (3.27 \pm 2.12) \times 10^{10}M_\odot\), therefore an UMBH. This provides a complementary approach to other high-z probes of SMBH mass, such as reverberation mapping (Blandford & McKee 1982; Bentz & Katz 2015) and AGN spectral fitting (Shen 2013.3). Unlike these methods, which require active accretion and depend on local Universe calibrations, the lensing technique offers a direct measurement independent of the SMBH’s accretion state.
In this paper, we analyse the Cosmic Horseshoe gravitational lens system (Belokurov et al. 2007), where the lens galaxy is one of the most massive strong gravitational lenses known to date. The lens galaxy is an early-type galaxy (ETG) at redshift \(\small z_i = 0.44\), possibly part of a fossil group (Ponman et al. 1994), and is notable for lensing one of its sources into a nearly complete Einstein ring (the Horseshoe). Additionally, a second multiply imaged source forms a radial arc near the centre of the lens galaxy. Due to the radial image formed very close to the centre, the inner DM distribution of the Cosmic Horseshoe can be studied in detail, as done by Schuldt et al. (2019.1). By simultaneously modelling stellar kinematics from long-slit spectroscopy and the positions of the lensed sources, Schuldt et al. (2019.1) found that the DM halo is consistent with a Navarro–Frenk–White (NFW; Navarro, Frenk & White 1997) profile, with the DM fraction within the effective radius (\(\small R_e\)) estimated to be between 60 per cent and 70 per cent. Moreover, their models include a point mass at the galaxy’s centre, reaching values around \(\small \sim 10^{10} M_\odot\), which could represent an SMBH; however, they did not pursue further investigations into this possibility. Using new integral-field spectroscopic data from the Multi Unit Spectroscopic Explorer (MUSE) and imaging from the Hubble Space Telescope (HST), we conducted a systematic modelling of the Cosmic Horseshoe system to reassess the evidence for an SMBH at the heart of the lens galaxy. We performed a self-consistent analysis of both strong gravitational lensing (SGL) and stellar dynamics, which demonstrated that the presence of an SMBH is necessary to fit both data sets simultaneously. This paper is structured as follows: In Section 2, we present the HST imaging data and MUSE observations, along with the kinematic maps used for the dynamical modelling. Section 3 briefly summarizes the lensing and dynamical modelling techniques, including the multiple-lens-plane formalism, the approximations adopted in this work, and the mass profile parametrization. In Section 4, we present the results from our fiducial model and alternatives models, which we use to address the systematics on the SMBH mass. In Section 5 we discuss our results and present other astrophysical implications. Finally, we summarize and conclude in Section 6. Unless otherwise, all parameter estimates are derived from the final sampling chain, with reported values representing the median of each parameter’s one-dimensional marginalized posterior distribution, with uncertainties corresponding to the \(\small 16^\text{th}\) and \(\small 84^\text{th}\) percentiles. Furthermore, throughout this paper, we adopt the cosmological parameters consistent with Planck Collaboration XIII (2016.1): \(\small \Omega _{\Lambda ,0} = 0.6911\), \(\small \Omega _{\text{m},0} = 0.3089\), \(\small \Omega _{\text{b},0} = 0.0486\), and \(\small H_0 = 67.74\) \(\small \text{km}\ \text{s}^{-1}\ \text{Mpc}^\text{-1}\).

When we compare their primitive cosmology with what modern science reveals—billions of galaxies, relativistic spacetime, the quantum-scale behaviour of matter, and black holes bending light into perfect circles—the contrast could not be more stark. The biblical description is not merely simplified; it is wrong on almost every measurable level. It has Earth at the centre, the stars as small lights, and the sky as a hard surface holding back water. Science, by contrast, uncovers a cosmos governed by consistent natural laws, tested and confirmed through observation and mathematics.
This is compelling evidence that an omniscient creator god did not write the Bible. If it had done, it could have contained truths about the nature of the cosmos that were unknown at the time, expressed in terms clear enough to be recognisable today—atoms, germs, the vastness of space, or even the basic structure of the solar system. Instead, what we find are the assumptions of scientifically illiterate Bronze Age people, drawing on local myths and imagination. The difference between their errors and the precision of modern astrophysics is not a matter of interpretation—it is a matter of fact.

Refuting Creationism - Evidence That Would Not Be There If The Bible Is True History.

Buried beneath a thick layer of silt containing a chaotic mixture of fossils from both nearby and distant land masses — the expected deposit of a supposed global genocidal flood — is... nothing. Such a layer should be observable worldwide, of course, but like at the archaeological sites in the Carpathians, it simply isn’t there.
Instead, what we find is an unbroken sequence of historical deposits stretching far beyond the time when creationists claim the Earth was magicked into existence. In other words, the evidence contradicts the Bible’s timeline and strongly refutes the notion of a global flood.
Importantly, this evidence isn’t the result of an attempt to disprove the Bible. Rather, archaeologists have simply uncovered facts that are starkly different from what one would expect if the Bible were the inerrant word of a creator god. A case in point: a team from Christian-Albrechts-Universität zu Kiel (CAU) investigating changes in social hierarchy associated with the introduction of agriculture in the Carpathian Basin.
According to expectations, the adoption of agriculture should have led to increased social inequality, as control of land and trade would concentrate power in the hands of a privileged elite. However, the researchers found no such evidence. Using house size as a proxy for social inequality — assuming that a ruling class would have built significantly larger dwellings — the team discovered that house sizes remained relatively uniform over the period.

Creationism Refuted - Don't Laugh At the Bible's Authors, They Were Only Doing Their Best!

Take a grain of rice and hold it between your thumb and forefinger at arm’s length while looking up at the night sky. The patch of sky hidden behind that tiny grain of rice probably contains thousands of galaxies—each with around half a trillion stars. Some of these stars are ancient, nearing the end of their tens-of-millions-of-years lifespans; others are just beginning to form from clouds of gas and debris left behind by older stars that exploded as supernovae.
What lies behind that grain of rice is a tiny fragment of a dynamic, evolving, ever-changing, and expanding universe. A universe of which our ancient prophets were completely unaware as they crafted imaginative descriptions of its origins—descriptions written just a few thousand years ago that portrayed it as a small, unchanging cosmos, with a flat Earth at the centre covered by a dome.
But let’s not be too hard on them. As they stood in their Canaanite pastures, the Earth must indeed have looked flat and small, and the sky would have seemed like the roof of a great tent, adorned with tiny lights and with the sun and moon suspended from it. To them, the Earth appeared fixed and immobile while the dome overhead turned slowly, or perhaps invisible spirits moved the lights across the heavens each night. They didn’t know where the sun went after sunset and imagined the moon might hide in a deep valley during the day.

Creationism Refuted - How Geophysics Could Have Influenced Human Development - 31,000 Years Before 'Creation Week'
Weird space weather seems to have influenced human behavior on Earth 41,000 years ago – our unusual scientific collaboration explores how
In that long stretch of Earth’s history before it was supposedly "created," according to creationist mythology—a span covering 99.9975% of the planet’s existence—a remarkable geophysical event occurred. Around 41,000 years ago, during a time when modern humans, Neanderthals, and Denisovans coexisted in Eurasia, a major disturbance in Earth’s magnetic field likely influenced human behaviour and may have hastened the disappearance of the Neanderthals.
This event, known as the Laschamps Excursion, was not a typical magnetic pole reversal, which Earth undergoes roughly every 100,000 years. Instead, the planet's magnetic field entered a chaotic state, weakening dramatically to around 10% of its usual strength and breaking into multiple, unstable poles.
Earth’s magnetic field normally shields the surface from ionising radiation by deflecting much of it towards the poles. With that protective barrier severely weakened, the planet would have been exposed to much stronger levels of ultraviolet radiation. The usual deflection of charged particles also produces the auroras, which during this period would have appeared across much of the night sky, including at lower latitudes—perhaps even near the equator—due to the multiple and shifting magnetic poles.
Although the Laschamps Excursion lasted only a few years, the environmental changes it triggered may explain behavioural shifts visible in the archaeological record. This is discussed in an article in The Conversation by Raven Garvey, Associate Professor of Anthropology at the University of Michigan; Agnit Mukhopadhyay, Research Scholar at the University of Alberta and Research Affiliate at Michigan; and Sanja Panovska, a Research Scientist at the GFZ Helmholtz Centre for Geosciences. Together with their colleagues, they have published their findings—open access—in Science Advances.
Incidentally, the archaeological evidence discussed here should not exist at all if the biblical flood narrative were true. Such a flood would have obliterated or buried this material beneath a chaotic layer of silt, destroying the stratified layers of sediment by which these finds are reliably dated—dating that is wholly inconsistent with the timeline of human history as derived from biblical mythology. Moreover, the Laschamps Excursion undermines any creationist claim that the Earth was created and fine-tuned especially for human life. If something as fundamental as magnetic polarity—and the UV protection it affords—can fail naturally due to processes in Earth’s core, then the idea of a specially designed planet collapses under its own absurdity.

Creationism Refuted - What Dinosaur Teeth Tell Us About Life 150 million Years Before 'Creation Week'
What Dinosaur Teeth Reveal About Life 150 Million Years Ago | Leibniz Institute
Some 150 million years before the mythical events of ‘Creation Week’—give or take a few thousand years—our distant ancestors were small, nocturnal, rodent-like mammals eking out an existence in a world dominated by colossal reptiles. Among these dominant life forms were the dinosaurs, thriving in a variety of ecosystems and feeding on plants or other animals, depending on their species.
As they ate, they unwittingly left behind a record of their diet etched into the microscopic wear patterns on the enamel of their teeth. Today, with the help of sophisticated analytical techniques, palaeontologists can read these patterns like a diary of prehistoric meals. And with each new discovery, such as the one published by a team led by Dr Daniela E. Winkler of Kiel University, the yawning gap between ancient mythology and modern science widens ever further. Their findings provide yet another decisive refutation of the simplistic narrative crafted by Bronze Age storytellers—later compiled into what some still insist is the inerrant word of an omniscient creator.
This latest blow to creationist pseudoscience comes in the form of an open-access paper, Dental microwear texture analysis reveals behavioural, ecological and habitat signals in Late Jurassic sauropod dinosaur faunas, published in Nature Ecology & Evolution.
The team focused on the teeth of sauropods—long-necked herbivorous dinosaurs such as Camarasaurus, Brachiosaurus, and Diplodocus — from the Late Jurassic Morrison Formation in North America and the Lusitanian Basin in Portugal. Using a method called Dental Microwear Texture Analysis (DMTA), they examined the microscopic wear patterns caused by feeding, revealing a fascinating spectrum of dietary strategies and environmental adaptations among different species.
What they found demolishes the notion of sauropods as a homogenous group of giant leaf-munchers. Instead, the microwear textures show distinct differences in feeding behaviour, likely linked to differences in available vegetation and habitat. For example, Camarasaurus appears to have consumed tougher, more fibrous plant material—perhaps conifers—while others such as Diplodocus may have specialised in softer vegetation like ferns or aquatic plants. These variations not only suggest niche partitioning, where species avoid direct competition by diversifying their diets, but also point to distinct ecological zones across the ancient landscapes they inhabited.
Even more telling is the comparison between North American and European sauropods. Despite being closely related, the differences in their dental microwear suggest adaptations to different environmental pressures and available flora, implying behavioural flexibility and evolutionary divergence shaped by their respective habitats.
Such complexity and diversity, preserved for over 150 million years in the microscopic textures of fossilised teeth, are a world away from the simplistic narratives of static 'kinds' created in a single week. Instead, we see a dynamic, evolving biosphere responding to ecological challenges—exactly what we’d expect in a world governed by natural selection and deep time.
Refuting Creationism - Party Time In Iran 1,000 Years Before 'Creation Week' - And The Flood Missed The Evidence

A thousand years before Earth was supposedly created—according to the Bronze Age myths that creationists regard as literal history—people were already feasting in the Zagros Mountains, at a site now known as Asiab in modern-day Iran. Then, in what must have been a strangely selective miracle, around 4,300 years ago—when, according to the same myths, a global flood wiped out all life on Earth—the remains of these ancient feasts remained completely untouched. Like countless other archaeological sites, Asiab shows no trace of the thick silt layer that such a cataclysmic flood would inevitably have left behind.
Long before the advent of agriculture, when humans still lived in scattered bands of hunter-gatherers, people gathered at Asiab for a communal feast. The exact reason—whether religious ceremony, marriage, funeral, or some form of tribal leadership event—can only be guessed at. But what is clear is that guests travelled long distances over mountainous terrain, bringing with them the carcasses of wild boar. These animals, dangerous to hunt and not commonly pursued by hunter-gatherers in the region, appear to have held special significance. Their presence suggests that hunting and transporting them was a display of prowess or status, perhaps reserved for prestigious guests.
This conclusion comes from a team of palaeontologists who examined the microscopic wear and isotopic signatures on the teeth of wild boar recovered from the site. (For more on how this technique works, see the AI information side panel.)
The international team, led by Dr Petra Vaiglova of the School of Archaeology and Anthropology at the Australian National University (ANU), has just published their findings open access in the journal Communications Earth & Environment.

Creationism In Crisis - Neanderthals With Different Cullinary Styles - 50,000 Years Before 'Creation Week'
Specialty of the house: Neanderthals at two nearby caves butchered the same prey in different ways, suggesting local food traditions
More embarrassment for creationists comes in the form of new evidence that Neanderthals were butchering and cooking meat in two caves in what is now Israel. Not only did this occur some 40,000 to 50,000 years before creationists believe the Earth was created, but it also shows that Neanderthal culture had diversified into distinct culinary traditions—even among populations inhabiting neighbouring areas.
The most damning evidence against creationist claims is, of course, the very existence of such archaeological remains. According to the biblical narrative of a global, genocidal flood just a few thousand years ago, this evidence simply should not exist. Such a cataclysm would have erased any trace of it—or at best buried it beneath thick layers of chaotic silt, jumbled together with fossils of plants and animals from distant land masses in no coherent stratigraphic order.
The evidence for Neanderthal cultural diversity comes from researchers at the Hebrew University of Jerusalem, who studied remains in the nearby caves of Amud and Kebara, located just 70 km apart.
What they found was a marked difference in how the two Neanderthal groups butchered their prey, including whether they processed the carcasses at the kill site or transported them back to their caves for preparation. There also appear to be differences in how the meat was cooked.
The researchers’ findings are published in the journal Frontiers in Environmental Archaeology.

Creationism Refuted - A Flint Arrowhead Embeded In A Human Rib Is Hurting Creationism
/ IPHES-CERCA

Around the time creationists claim Earth was undergoing a global flood — a mass genocide by drowning, supposedly enacted by a deity - a belief based solely on the origin myths of a Bronze Age Middle Eastern pastoralist tribe — people in the Pyrenees were engaged in violent conflict, using bows and arrows. Unlike biblical mythology, this insight is grounded in tangible evidence: a human rib bone with a flint arrowhead still embedded in it. Remarkably, the injury had healed before the individual died, suggesting they survived the attack for some time. The rib was found in a mass grave at Roc de les Orenetes (Queralbs, Girona), alongside the remains of several others, many of whom showed signs of trauma from blunt or sharp weapons, particularly to the head and upper body.
The timing of this violence — dated to between 4,100 and 4,500 years ago — is problematic for biblical literalists. If the Genesis flood had truly occurred as described, these remains should either have been destroyed or buried beneath a thick layer of flood-deposited silt, mixed with the remains of animals and plants not native to the region. Alternatively, one must believe that just a few years after a supposed global reset that reduced humanity to eight survivors, their descendants had multiplied sufficiently to form warring groups in the mountains of what is now northern Spain.
And yet, these individuals show no sign of having heard of Noah, his family, or the god who allegedly saved them. There’s no indication of the monotheistic religion supposedly preserved aboard the ark. If the flood story were true, the moral lesson it was intended to deliver seems to have been forgotten almost immediately, everywhere except among a small group in the Canaanite hills.
This discovery joins a growing list of archaeological findings that contradict the flood narrative. Far from showing a global cataclysm, the archaeological record reveals continuous human habitation before, during, and after the time the flood is supposed to have occurred—with no signs of interruption, no replacement by a Near Eastern culture, and no characteristic flood-deposited sediment layer.
It’s almost as if the global flood never happened. Not only is there no geological or archaeological evidence supporting it, but what evidence we do have consistently contradicts it. This find from the Pyrenees is yet another example.

Refuting Creationism - What a Tiny Part Of The Universe Looked Like 150,000 Before 'Creation Week' - Hubble Space Telescope
Acknowledgement: M. H. Özsaraç

The ESA/Hubble photograph of the week offers a glimpse into a vast and ancient universe—one that starkly contrasts with the primitive cosmology described in the Bible. The image captures a globular cluster in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way, located some 160,000 light-years from Earth. What we’re seeing, then, is a snapshot of this cluster as it was 160,000 years ago—long before the writers of the Bible imagined their god creating a small, flat Earth with a dome over it, to which the sun, moon, and stars were affixed, somewhere in the vicinity of the Canaanite hills.
At the time, the light we’re now seeing began its journey across space, early humans in Africa were evolving the skills and traits that would eventually allow them to leave the continent and colonise new territories. According to [a recent study](https://www.science.org/doi/10.1126/science.adi1768), there had been earlier migration attempts northward, but these failed to establish lasting populations for reasons still debated by researchers.
What this photograph shows us—quite literally—is a universe that predates the biblical account of creation by well over 150,000 years, and a cosmos that bears no resemblance to the geocentric, dome-covered world described in Genesis. While we can’t know exactly how our early ancestors viewed the night sky, their understanding was likely not very different from that of the later Bronze Age storytellers who wrote the biblical texts. Both were constrained by limited technology, and neither had any inkling of galaxies, light-years, or cosmic timescales.

Refuting Creationism - What Our Prophets Never Told Us

To celebrate its third anniversary, astronomers used the NASA/ESA/CSA James Webb Space Telescope to scratch beyond the surface of the Cat’s Paw Nebula (NGC 6334), a massive, local star-forming region.
This is what they saw. Compare it to the description of the universe in the Bible - a small flat planet with a dome over it at the center, with the sun and moon attached to the dome and stars stuck to its underside, able to be shaken lose in earthquakes.
Here is what the late great Carl Sagan had to say about how religions view the universe:

Creationism Refuted - Wooden Tools - From 290,000 Years Before 'Creation Week'
2025 | Oldest wooden artefacts ever found in East Asia reveal plant-based diet of ancient humans - University of Wollongong – UOW
The childish notion of creationism took another battering today with the announcement that an international team of researchers, including University of Wollongong archaeologist Professor Bo Li, has unearthed a set of wooden tools in south-west China dating to approximately 300,000 years ago. That places them a full 290,000 years before creationists believe the Earth was formed, situating their manufacture and use within the 99.9975% of Earth’s history that occurred before the so-called ‘Creation Week’.
This date significantly predates the appearance of anatomically modern humans outside Africa. The exact identity of the archaic hominins who made and used these tools is uncertain — possibly early Denisovans, Homo heidelbergensis, or perhaps H. erectus. What we can say with confidence is that these hominins stand in stark contradiction to the Bronze Age origin myths recorded in the Bible, which many creationists insist are literal historical accounts.
The usual creationist response to such findings is to reject them outright as fabrications, the result of flawed methodology, or deliberate deception. However, the dating of these artefacts relies on a technique refined by Professor Li called electron spin resonance (ESR), which measures the time elapsed since the artefacts were buried. (See the side panel for further details.)

Refuting Creationism - The Mass Extinction 252 Million Years Before 'Creation Week'
New fossils reveal climate tipping point in most famous mass extinction | University of Leeds
Creationists claim that Earth is only a few thousand years old and that it was created perfectly and finely tuned for life—brought into existence without ancestors, from nothing, by means of supernatural command. Their evidence for this extraordinary claim rests on the beliefs of Bronze Age pastoralists who imagined Earth as small, flat, and covered by a solid dome. These ancient myths were eventually written down, bound up in a book later declared by people with a vested interest, to be divinely inspired and historically accurate.
Science, by contrast, presents a very different picture. Far from being a perfect and finely tuned haven for life, Earth is a dynamic and often hostile planet. Life persists here not because conditions are universally benign, but because a small number of organisms have evolved to thrive within narrow environmental niches. Throughout Earth’s long history, global conditions have periodically tipped into extremes so severe that they triggered mass extinction events. Unlike creationist claims, these conclusions are supported by tangible, testable evidence.
One such event—known as the Great Dying—occurred around 252 million years ago, relatively recent in the planet’s \~4.5 billion-year history. This catastrophe, the most severe extinction event known, was likely triggered by intense volcanic activity that caused a rapid and sustained rise in global temperatures. The resulting climate shift led to the collapse of tropical forests, which in turn reduced the planet’s capacity to absorb atmospheric carbon, driving further warming. This cascade of ecological breakdown led to the loss of most marine species and widespread collapse of terrestrial ecosystems.
The outcome was a planetary heatwave that lasted for approximately five million years.
New evidence for the role of rainforest collapse in both the onset and the recovery from the Great Dying has been presented by an international team of scientists, led by researchers from the University of Leeds and the China University of Geosciences in Wuhan. Their findings are detailed in a recent paper published in Nature Communications and summarised in a news release from the University of Leeds.

Refuting Creationism - The Universe Is Much Grander Than Our Prophets Ever Guessed.
Vera C. Rubin Observatory Unveils First Sky Images Taken with World's Largest Camera | CNRS
And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. And God set them in the firmament of the heaven to give light upon the earth, And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.(Genesis 1.16-18)
Just imagine, there are adults alive today who believe that is the best available description of the universe, far surpassing for detail and accuracy anything that modern science, with all its sophisticated equipment can produce!
Compare it with what science is showing us it is really like and ask yourself whether a real creator god could have got it so badly wrong when describing its own creation.

Refuting Creationism - How Dogs Spread Across The Americas - Then Survived The Legendary Biblical Global Flood
Ancient DNA reveals new clues about the incredible journey of dogs in the Americas | University of Oxford
According to the Bible, all living things outside Noah’s Ark were destroyed once Noah, his family, and his chosen animals were safely sealed inside (Genesis 7:4). This supposedly happened around 4,000 years ago, according to the biblical narrative — which creationists firmly believe to be inerrant history.
The snag is, the evidence simply doesn’t support that timeline—or a global flood involving mass extinction by drowning. Not only would such a flood have left a distinctive global deposit of sediment, containing a chaotic mix of ancient and modern animal and plant species from disconnected continents, but it would also have erased all archaeological traces of earlier civilisations and palaeontological evidence of past life. In effect, it would have reset the clocks of both archaeology and palaeontology to start around 4,000 years ago.
Unfortunately for biblical literalists, that’s not what we see. The predicted tell-tale layer of silt is conspicuously absent. Instead, both archaeology and palaeontology reveal a pattern of uninterrupted occupation of the planet by animals and humans stretching back tens of thousands—and, in the case of animal and plant species, hundreds of millions—of years. For anatomically modern humans, there is a consistent archaeological record documenting their spread across all land masses (except Antarctica), during which they domesticated animals such as dogs, which migrated alongside them.
One example of this pattern — the migration of domestic dogs with humans into the Americas between 7,000 and 5,000 years ago — has just been published in Proceedings of the Royal Society B, by an international team of scientists led by Dr Aurélie Manin from the School of Archaeology at the University of Oxford. They have shown that all South American dogs prior to the arrival of Europeans, trace their ancestry back to a single female. One strain — the Mexican Chihuahua - still shows evidence of that ancestry.

Refuting Creationism - How We Know The Bible Was Made Up By Scientifically-Illiterate People

The Bible contains no scientific insights or understanding beyond what would have been known to Bronze Age pastoralists—what Christopher Hitchens aptly described as the "fearful infancy of our species." Their knowledge was naturally constrained by the absence of scientific instruments, a lack of understanding of the planet's history, and a worldview shaped by tribal dogma and magical thinking.
Had the Bible truly been written or inspired by the deity it describes — as a vital message to humanity from the creator of the universe — one might reasonably expect it to contain some revelations unknown to its time. Yet it offers nothing by way of evidence to support such a claim. There is no mention of germ theory, no understanding of cells or cellular life, no grasp of atoms, electricity, or metabolic processes like photosynthesis and respiration. All living things are described as strictly male or female, with no recognition of genetics, hermaphroditism or parthenogenesis — except for a single, supposedly miraculous human birth of a genetically impossible male child. In short, the text contains nothing that was not already known or assumed until the development of tools like the microscope and telescope, and much of it was clearly and demonstrably wrong.
The Bible’s authors were storytellers, not scientists. Their goal was not to challenge the cultural assumptions of their time but to frame them within a compelling narrative.
Because religions are not founded on tested hypotheses or objective facts but rather on the best guesses of uninformed people, any alignment with modern scientific understanding is coincidental, not predictive. For example, the biblical phrase *"Let there be light"* is sometimes interpreted as metaphorically reflecting the early high-energy state of the universe following the Big Bang. But there is no indication that the authors understood photons, particle physics, or the quantum nature of space-time. Nor did they suggest that the universe originated nearly 14 billion years ago in a quantum fluctuation of a non-zero energy field.
Recent discoveries illustrate just how far modern science has advanced beyond anything conceivable to ancient authors. For instance, an international team of scientists has recently found evidence suggesting the existence of heavy particles during the universe's first microseconds—particles that influenced the behaviour of other matter. This discovery, utterly incomprehensible to a Bronze Age worldview, is detailed in a peer-reviewed article published in Physics Reports.
