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.

Malevolent Design - How Having a Bigger Brain Made Humans More Vulnerable To Cancer Than Our Chimpanzee Cousins

A Single Genetic Mutation May Have Made Humans More Vulnerable to Cancer Than Chimpanzees | Newswise

According to creationists, humans are the designer’s special creation, and the Universe, Earth, and all life upon it were created solely for our benefit.

If that were the case, one might reasonably expect human design to be uniquely perfect—free from disease and physical defects. Yet, paradoxically, we are more prone to cancer than our closest evolutionary relatives, the other great apes. Recent research from the UC Davis Comprehensive Cancer Center suggests that this heightened cancer susceptibility may be linked to the very mutation that enabled us to develop our comparatively large brains.

It’s almost as though the 'designer' either deliberately endowed humans with a cancer-promoting mutation or failed to anticipate the consequences of the so-called "complex specified genetic information" (© William A. Dembski / Discovery Institute) introduced to facilitate brain growth—and then neglected to revise the design when the flaw became evident. But, of course, being omniscient, we have to assume, if we accept creationists dogma for the sake of argument, it knew full well what the consequences of its design would be and designed them with that consequence in mind.

The theory of evolution, of course, precisely predicts these kinds of suboptimal trade-offs and their consequences. As an undirected, uncaring process, evolution is concerned solely with reproductive success—not with long-term health, perfection, or ideal design.

According to the biblical narrative, the entire human population of Earth was reduced to just eight related individuals around 4,000 years ago, following a global, genocidal flood — a flood which, curiously, left no trace.

Now, as is almost invariably the case, new scientific evidence is entirely inconsistent with that narrative. The genetic analysis of an individual who lived and died in Egypt between 4,500 and 4,800 years ago shows that he was approximately 80% North African, with the remaining 20% of his DNA tracing to the vicinity of Mesopotamia.

Historical evidence also shows that, long before the supposed global flood, agriculture-based civilisations had been established in both Egypt and Mesopotamia. These societies had already formed trading networks and cultural connections, and left behind artefacts — including stone structures and buried remains — which would have been completely obliterated by the kind of flood described in the Bible.

More telling still is that, by 4,500 years ago, the human population — which, according to the biblical account, had only recently descended from a single family via incestuous inbreeding — had already diversified to the point that measurable genetic differences existed between the Egyptian and Mesopotamian populations. This diversity is what made such DNA analysis possible in the first place.

The analysis of this individual’s genome — the oldest Egyptian DNA recovered to date — was carried out by researchers from the Francis Crick Institute and Liverpool John Moores University (LJMU), UK. They have just published their findings, open access, in Nature.

Malevolent Designer - How A Common Virus Sneaks Past Our Immune System And Causes Birth Defects

Scientists Uncover How a Common Herpes Virus Outsmarts the Immune System | School of Medicine | University of Pittsburgh.

Intelligent (sic) Design creationists have painted themselves into a corner.

Two of their most prominent arguments—irreducible complexity (Michael J. Behe) and complex specified information (William A. Dembski)—are intended to demonstrate the involvement of an intelligent designer in the natural world. But when these same criteria are applied to harmful parasitic organisms, such as the common herpesvirus (cytomegalovirus), which is the leading infectious cause of birth defects in the United States, the implication is that this virus too is the product of intentional design by the same creator that ID proponents insist is responsible for all life.

Within the framework of Intelligent Design creationism, the conclusion is inescapable: their designer deity—typically equated with the omniscient, omnibenevolent god of the Christian Bible—knowingly and deliberately created a pathogen that causes immense suffering. If ID logic is followed consistently, their deity is not a benevolent creator but a malevolent force that engineers disease and deformity with full foreknowledge of the consequences.

The only escape from this theological and philosophical bind is for ID creationists to refute their own criteria—to claim that irreducible complexity and complex specified information are compelling proof of design when found in beneficial biological systems, but somehow irrelevant or invalid when found in destructive pathogens. In doing so, they are forced to hold two mutually exclusive beliefs simultaneously.

In reality, these hallmarks of design touted by ID advocates are common outcomes of natural evolutionary processes — especially arms races between host defences and parasitic invaders. These processes are inherently unguided and wasteful, which in itself refutes the idea of intelligent planning.

Another striking example of this evolutionary struggle has just been published in Nature Microbiology by researchers from the University of Pittsburgh School of Medicine and the La Jolla Institute for Immunology. Their study sheds light on how the herpesvirus has evolved sophisticated strategies to evade the immune system — a feature that ID logic would classify as evidence of "design."

Refuting Creationism - Evidence of Humans In America 13,000 Years Before 'Creation Week'

Human footprints at White Sands National Park in New Mexico, reported in 2021, show that human activity occurred in the Americas as long as 23,000 years ago – about 10,000 years earlier than previously thought. A new U of A study supports the 2021 findings.

Stratum 1 is exposed in the foreground (comprising the eastern margin of Alkali Flat), but in this photo, it is dried out and covered with a thin sheet of eolian gypsum sand. The finely bedded sands and muds of Stratum 2A comprise the low escarpment in the middle ground, expressed by the thin, horizontal ledges formed by differential weathering of the stream beds. The trench exposing human tracks in Stratum 2A is at the left.

It was likely more extensive given the >4 m of lake beds at “G.” The two field areas (red dots) are as follows: “G” is the area of Gypsum Overlook, the Central study area, and WHSA Locality 2; “Loc 1” is a stratigraphic section along the west margin of Alkali Flat. The brown pattern at G is the area of exposures of deposits linked to paleolake Otero and overlain by truncated Holocene dunes (31). The inset shows the location of the White Sands and the Tularosa Basin within New Mexico [based on figure 1 in (31)].

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.

Creationism's ever-shrinking, gap-shaped creator god has just lost a little more ground. New research suggests that the formation of basic organic molecules may have been far easier under early Earth conditions than previously thought. Remarkably, scientists have found that urea—a key organic compound—can form spontaneously from ammonia and carbon dioxide on the surface of water droplets. This process requires no catalysts, no high pressure or heat, and consumes minimal energy.

Although vitalism was refuted as early as 1828 — decades before Darwin — creationists still claim that life cannot arise from non-living matter. Yet they quickly retreat when asked how dead food becomes living tissue, or what exactly they mean by ‘life’: a substance, a process, or some kind of magical force. In reality, life is a set of chemical processes, and at its core, it’s about managing entropy—using energy to maintain order against the natural drift toward disorder.

The discovery was made by researchers at Eidgenössische Technische Hochschule (ETH) Zürich in collaboration with colleagues from Auburn University in Alabama, USA. Their findings have just been published in Science.
