Metabolic Analyses of Animal Fossils Helps Scientists Reconstruct Million-Year-Old Environments

The bad news for creationism continues unabated. Scientists led by Professor Timothy G. Bromage of the Department of Molecular Pathobiology at New York University College of Dentistry have developed a technique that opens an entirely new window onto the deep past. By analysing metabolites preserved in fossilised bones, the researchers are able to extract detailed biological and environmental information from animals that lived between 1.3 and 3 million years ago.

The team have published their findings in Nature, describing a method that pushes palaeobiology well beyond traditional morphology-based reconstruction.

The significance of this technique lies in its ability to reconstruct ancient environments with remarkable precision. From the chemical signatures locked within fossil bone, researchers can infer temperature, soil conditions, rainfall patterns, vegetation, and even the presence of parasites. The resulting picture is one of ecosystems changing over time, with animals adapting in step with shifting environments — exactly what evolutionary theory predicts, and wholly incompatible with the childish notion of magical creation a few thousand years ago or a recent biological reset caused by a genocidal flood.

Creationism Refuted - Highly Accurate Dating of Dinosaur Eggs

The Gobi Desert, where many dinosaur eggs have been found.

Dinosaur eggshells unlock a new way to tell time in the fossil record | Stellenbosch University

This paper will have creationists searching for reasons to dismiss evidence that would, if they were prepared to accept it honestly, force them to concede that their beliefs are wrong. It reports a discovery by researchers at Stellenbosch University showing that dinosaur eggshells can be dated with a high degree of precision using an already well-established technique: uranium–lead (U–Pb) radiometric dating.

Until now, U–Pb dating has been most famously applied to zircon crystals in volcanic ash, where the age can be determined by measuring the ratio of radioactive uranium isotopes to the stable lead isotopes produced by their decay. In this study, however, the same underlying principles are applied to calcite crystals preserved in dinosaur eggshells.

The scientists have published their method, open access, in the journal Communications Earth & Environment.

Abiogenesis News - Scientists Create Geothermal Vents In A Lab - And they Make Precursors For Life

A venting black smoker emits jets of particle-laden fluids. The particles are predominantly very fine-grained sulfide minerals formed when the hot hydrothermal fluids mix with near-freezing seawater. These minerals solidify as they cool, forming chimney-like structures. “Black smokers” are chimneys formed from deposits of iron sulfide, which is black. “White smokers” are chimneys formed from deposits of barium, calcium, and silicon, which are white.

Underwater thermal vents may have given rise to the first molecular precursors of life

A favourite disingenuous creationist tactic is to keep challenging science to achieve something that seems impossible—such as replicating the conditions of a deep ocean thermal vent to demonstrate that this could have been where life began. The trap is then to either gloat over science’s failure or to shift the goalposts and proclaim that any success merely proves that intelligence is required to create life.

So, we can almost guarantee that the news that a team of scientists at Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) in São Paulo, Brazil, have replicated not the thermal vents themselves but the chemical reactions believed to have occurred within them—and shown that these reactions do indeed produce the precursors of living systems—will be presented by creationists as supposed proof of the role of intelligence in the process.

The fallacy, of course, is that a laboratory experiment merely establishes the conditions under which natural forces can operate. By contrast, intelligent design advocates insist that an intelligent entity, working to a plan, must actively direct those natural forces to make chemistry and physics do something they supposedly couldn’t do on their own. Such is the intellectual dishonesty of many creationists that this distinction is either too subtle for them to grasp—or they deliberately ignore it.

Hot springs in Japan give insight into ancient microbial life on Earth – ELSI｜EARTH-LIFE SCIENCE INSTITUTE

It’s been a dreadful week for creationists as yet another published paper undermines one of their favourite claims and further reduces the god-shaped gap on which they increasingly depend — the so-called abiogenesis gap. This argument rests on the delusional assumption that if science has not yet fully explained something, then it never will — and therefore creationism wins by default. The history of science, of course, shows the opposite: today’s mysteries are tomorrow’s discoveries.

This time, the blow comes from a publication in the journal Microbes and Environments, which describes how five hot springs in Japan provide natural analogues of the conditions in which the first living organisms could have evolved. These springs are rich in diverse chemical and thermal gradients, making them excellent testbeds for exploring how life can thrive in extreme conditions and use non-traditional energy sources.

The study was conducted by a team led by Fatima Li-Hau, then a graduate student at the Earth-Life Science Institute (ELSI), Tokyo Institute of Science, with Associate Professor Shawn McGlynn as her supervisor. Their work focused on the microbial communities found in these hot springs, which range from moderately warm to boiling.

Refuting Creationism - Scarey Days For Creationists As More Signs of Life on Other Bodies Are Found

ESA - Cassini proves complex chemistry in Enceladus ocean

In a soccer manager’s jargon, this is squeaky bum time for creationists who cling to the notion that science will never demonstrate that abiogenesis is even possible, let alone explain how it happened.

Squeaky bum time for a football manager is when the team’s league position — and with it qualification for European tournaments, and often the manager’s job — hangs on a single unpredictable result.

So it is with creationism. One single piece of definitive evidence that life has arisen independently on another world in the Solar System, or on an exoplanet orbiting a distant sun, would comprehensively consign creationism to the dustbin of history where it has been struggling to avoid ending up since 1859. Such a discovery would refute the claim that ‘life from non-life’ is impossible. Instead, it would show that under the right conditions, life is simply a natural product of chemistry and physics.

And the signs are as dire for creationism as for the embattled football team that finds itself 2–0 down in stoppage time. Scientists at the European Space Agency have just announced the detection of possible signs of life in the ocean beneath the icy crust of one of Saturn’s moons, Enceladus, as revealed by NASA’s Cassini spacecraft. This follows close on the heels of strong evidence that life once existed on Mars.

The tentative evidence from Enceladus points to processes in its subsurface ocean producing organic precursors to amino acids — the basic building blocks of proteins and a fundamental requirement for prebiotic chemistry that could eventually lead to organised cells. Researchers also report the detection of previously unknown molecules, including aliphatic and (hetero)cyclic compounds, esters, alkenes, ethers, and tentatively nitrogen- and oxygen-bearing compounds.

These organics were detected by Cassini’s Cosmic Dust Analyzer (CDA) in ice crystals ejected in plumes through cracks in Enceladus’ ice covering. These plumes are thought to form when water seeps into the moon’s rocky core, is heated, and then forced back up to the ocean floor as hydrothermal vents — much like those found in Earth’s oceans. The hot water increases the pressure in the subsurface ocean until the ice cracks and jets of vapour and ice crystals erupt. Most fall back to the surface, but some escape Enceladus’ weak gravity and contribute to one of Saturn’s rings, within which the moon orbits.

Refuting Creationism - Scientists Might Have Got Something Wrong - But Not As Wrong As The Bible's Authors Did.

Minute witnesses from the primordial sea | ETH Zurich

Scientists at Eidgenössische Technische Hochschule (ETH) Zürich have discovered evidence that may force us to rethink how Ice Ages and complex life began. By studying tiny iron oxide grains called ooides, they found that dissolved carbon dioxide in the oceans between 1000 and 541 million years ago was 90–99 percent lower than today — far too low to have triggered an Ice Age or the rise of multicellular organisms.

For creationists, this creates a dilemma. Whatever did cause these events, it happened hundreds of millions of years earlier than their literal reading of the Bible allows. Science may revise its conclusions when new evidence emerges, but it is nowhere near as wrong as the Bible’s authors—who missed the truth by billions of years.

This difference highlights the contrast between science and religion. Science asks, “What does the evidence show?” and adapts accordingly. Religion demands blind faith, treating doubt as a weakness.

Creationists boast that their “truth” never changes, but the reality is that what doesn't change is the mind of a creationist who is immune to evidence, deductive logic and analytical reasoning. Refusing to change your mind in the light of evidence is intellectual bankruptcy - the hallmark of dogma, not wisdom.

Refuting Creationism - Why Consciousness Doesn't Need A God To Explain it

Major theories of consciousness may have been focusing on the wrong part of the brain

Spend a few days in a Creationism vs. Science group on social media and, before long, you’ll be told that science can’t explain consciousness—because, so the argument goes, matter can’t become self-aware, and consciousness can’t arise from nothing.

In other words, you’ll encounter yet another variation on the combined argument from incredulity, the “god of the gaps” fallacy, and the false dichotomy—presented as if they were sound logic against science, and, since only two possibilities are assumed, in favour of the locally popular version of a creator god.

The more fundamentalist creationists will, of course, also try to “prove” that only humans possess real consciousness, since this sets us apart from other animals and grants us the supposedly unique ability to worship their particular god.

But what creationists can never explain is this: if consciousness is not a function of neurophysiology — in other words, the product of chemistry and physics — why can it be abolished with chemicals such as anaesthetics, or by physical injury?

This makes it all the more interesting that a recent paper in Neuroscience & Biobehavioral Reviews by Peter Copple of the Consciousness and Cognition Lab, Department of Psychology, University of Cambridge, UK, reviewing the sufficient conditions for consciousness, makes no suggestion that consciousness is divorced from neurophysiology or that it requires supernatural intervention to explain.

He makes similar points in an article in The Conversation, which is reproduced here under a Creative Commons licence.

Refuting Creationism - How Earth Was Really Made - No God-Magic Needed

High-energy Venus Impacts

An SwRI-led team compared the early impact history of Venus and Earth, determining that Venus experienced higher-energy impacts that created a superheated core. Models show these conditions could create Venus’ extended volcanism and younger surface.

Evolution of Terrestrial Planets
A new SwRI-led paper highlights the scientific progress made in understanding the evolution of terrestrial planets, including the effects of late large impacts on pre-existing modes of tectonics. For instance, the Earth experienced transient subduction, when one tectonic plate slides beneath another. Because Venus’ surface is covered by a single plate, a high-velocity impact led to a superheated core and long-lived volcanism. On Mars, a large, low-velocity impact facilitated variations in its hemispheres. Impacts also modify the atmospheres of terrestrial planets in profound ways, including eliminating or supplementing existing gases.

Creationist myths describe Earth as a flat world under a dome at the centre of the Universe, made just a few thousand years ago. The real story is far more extraordinary: a fragile chain of chance events and natural forces that made life possible on this small rocky planet.

Earth orbits an ordinary star on the edge of the Milky Way, one of billions in one of trillions of galaxies. That it exists at all is down to gravity, physics, and luck. Out of this came a beautiful world teeming with life—including one species able to marvel at the Universe and ask how it all began, and in it's fearful, ignorant infancy, make up the myths to explain it that now pass for science in some scientifically backward cultures.

One early collision with a smaller planetoid gave us the Moon, tides, and seasons; this or a later impact may, according to this study, be responsible for tectonic plates, giving us a forever changing, dynamic planet, driving evolutionary divergence. While not required for life to appear, these events shaped the planet into the diverse, life-rich world we know today.

'Potential biosignatures' found in ancient Mars lake | Imperial News | Imperial College London

Scientists analysing data from NASA’s Perseverance rover have reported a tantalising discovery from Jezero Crater on Mars: rocks rich in minerals and chemical patterns that could represent potential biosignatures — the traces left behind by ancient life. The findings, published by an international team led from Imperial College London, point to the remains of an ancient lake where conditions may once have been favourable for microbial life to take hold.

The evidence comes from mudstones, clays, silica, iron-phosphate and iron-sulphide nodules, along with carbon compounds that appear to have undergone redox reactions. On Earth, such processes are often associated with biology, though the researchers are careful to stress that non-biological explanations are still possible. It will take the return of rock samples to Earth, with far more powerful laboratory techniques, before firm conclusions can be reached.

Chemists recreate how RNA might have reproduced for first time | UCL News - UCL – University College London

The day creationists dread — the final closure of their favourite god-shaped abiogenesis gap — moved a little closer last May, when scientists at University College London (UCL) announced that they had shown how the first RNA could have reproduced. In a selective environment with competition for resources, this would have led inevitably to ever-increasing efficiency in replication, kick-starting the whole evolutionary process and the emergence of self-organising systems (or “life”) from prebiotic precursors (or “non-life”). This is, of course, the very process that creationists insist is “impossible”, clinging to the idea that “life” is some magical essence that must be granted by a supernatural deity.

When this God-shaped gap is finally and conclusively closed — as all the others have been — creationists will need to scramble once again to reframe their beliefs and cling to whatever shrinking space remains for their god. Just as their old claim that evolution was “impossible” collapsed, to be replaced with notions of a short burst of warp-speed evolution “within kinds” after “The Flood” (and supposedly still happening today, but conveniently “guided” by God), so too will abiogenesis inevitably be rebranded as yet another process directed by divine intention — naturally, with the eventual production of (American) humans as the goal.

The torus is oriented vertically and nearly edge-on from our perspective, and it intersects with bubbles of gas enclosing the star. The bubbles appear bright red in this image, illuminated by the light from helium and neon gas. Outside the bubbles, jets traced by emission from ionised iron shoot off in opposite directions.

JWST observations of Butterfly Nebula reveal how cosmic dust is made in space - News - Cardiff University

There’s a double whammy for creationists in this new paper. Not only does it expose the Bible’s description of the Universe as laughably naïve, but it also shows how organic molecules — in the form of polycyclic aromatic hydrocarbons (PAHs) — that may have formed the basis of life on the prebiotic Earth, could have been created in deep space and later incorporated into our planet either at its formation or via impacts from space debris.

The paper, by a team of scientists led by Cardiff University, has just been published in Monthly Notices of the Royal Astronomical Society. Using data from the James Webb Space Telescope (JWST), the researchers reveal how stars generate space dust, organic material, and the fundamental building blocks from which rocky planets like Earth are formed. Their study focuses on the Butterfly Nebula (NGC 6302), a spectacular stellar remnant.

What Are PAHs?

Polycyclic aromatic hydrocarbons (PAHs) are complex organic molecules made of fused benzene rings — essentially arrangements of carbon and hydrogen in hexagonal patterns. On Earth, they are often associated with combustion (for example, in car exhaust fumes, cigarette smoke, or charred food). In space, however, they form naturally in the outflows of dying stars and in the dense molecular clouds that give rise to new stars and planetary systems.

PAHs are of great interest to astrobiologists because they are thought to be among the earliest organic compounds to have existed in the Universe. They can undergo chemical transformations to form more complex molecules, including amino acids and nucleotides, which are the essential components of life. Their presence in meteorites and interstellar dust suggests that the seeds of life were widespread long before Earth even formed.

Refuting Creationism - Oceanic Oxygenation Spured Rappid Evolution - 390 Million Years Before 'Creation Week'

How oxygen made the deep ocean home to animals, spurring rapid evolution | UW News

Another wave of reality breaks over the impervious rocks of creationist dogma, in the form of news that an international team of researchers led by the University of Washington has shown a correlation between the rapid radiation of marine vertebrates and the evolution of plants on land. As trees and other vascular plants spread, more atmospheric carbon became locked into their woody stems, reducing carbon dioxide levels. At the same time, increased photosynthesis raised atmospheric oxygen levels, which in turn oxygenated the oceans, making oxygen available in depths that had previously been anoxic.

Creationists will, of course, need to ignore the fact that this finding flatly contradicts their claims that evolution only occurs within “kinds” and that all diversification happened in a brief burst of warp-speed evolution following a genocidal global flood some 4,000 years ago. The timeline alone is utterly inconsistent with their favourite creationist fairy tale.

Scientists once believed this major oxygenation event had occurred about 500 million years ago, but the new research shows that episode was short-lived. A more significant oxygenation occurred around 390 million years ago. Initially, oxygenation would have taken place in shallow coastal regions where vertebrates first evolved. As oxygen penetrated deeper into the oceans, vertebrates followed into the newly opened niches, leading to a rapid proliferation of jawed vertebrate species — the ancestors from which terrestrial tetrapods later evolved.

The team reached their conclusions after measuring selenium isotopes in 97 sedimentary rock samples from five continents, dated between 252 and 541 million years ago. These rocks had been deposited near the edges of continental shelves, where shallow seas transition into the deep ocean. Selenium occurs naturally in several isotopic forms, and the ratios in which they were deposited depend on the level of oxygen dissolved in seawater. These isotopic signatures thus provide an indirect measure of oxygenation levels at the time the rocks were laid down.

The frequent creationist assertion that abiogenesis is impossible without invoking supernatural intervention has taken another significant blow with the recent open‑access publication in Proceedings of the National Academy of Sciences (PNAS). The study, Self‑reproduction as an autonomous process of growth and reorganization in fully abiotic, artificial and synthetic cells, demonstrates, for the first time, the successful laboratory creation of simple, non‑biochemical self‑reproducing vesicle‑like systems exhibiting Darwinian evolution: each generation varies slightly in traits that influence their ability to replicate.

This breakthrough indicates that such self‑sustaining systems could plausibly arise through natural processes, and gradually—through Darwinian mechanisms—evolve into the first simple biological life forms, from which all life subsequently diversified. It also lends empirical support to the principle that when self‑replication with small variation occurs in a selective environment, evolution in the direction of increased fitness is inevitable.

The evolution of life may have its origins in outer space

If you listen to creationists, you might be persuaded to believe that the formation of inorganic chemicals—often deliberately conflated with 'life' to evoke an emotional reaction—is, for all practical purposes, impossible without the intervention of a supernatural intelligence. This is, of course, nothing more than the familiar creationist fallback: the god of the gaps argument, coupled with a false dichotomy, and dressed up with a spurious veneer of mathematical ‘proof’.

But this tactic suffered yet another fatal blow recently with the publication of a study led by Abubakar Fadul of the Max Planck Institute for Astronomy (MPIA), which reported the discovery of organic molecules in the protoplanetary disc surrounding the young star V883 Orionis. This finding provides compelling evidence that the formation of prebiotic molecules can begin even before planets form—suggesting that Earth may have developed with a complement of organic compounds already present in the accretion disc from which it emerged.

An alternative, but equally plausible, hypothesis is that these molecules could have been delivered by meteorites or other interplanetary bodies.

Abiogenesis News - Not Random Chance Or Divine Magic But Natural Selection

Where did RNA come from? | Scripps Research

One fallacy with which anyone who has tried to engage a creationist in debate will soon become familiar is the false dichotomy. This is where a creationist attempts to make a "god of the gaps" argument appear logical by presenting it as a binary choice between something so simplistic or absurd that no serious scientist would argue for it—and "God did it!" In doing so, they ignore the actual scientific explanations and exclude all other plausible natural mechanisms.

A classic example of this is the argument that abiogenesis—often deliberately misrepresented as the spontaneous assembly of a complex, living cell from inorganic materials—is far too improbable to have occurred by chance alone, and therefore must have required a supernatural intelligence. In their minds, the very existence of complex life is "proof" of their particular deity.

This line of reasoning overlooks the crucial role played by natural processes, such as chemistry and physics, and what amounts to an evolutionary process at the molecular level. In such a process, chemical pathways that are more efficient at producing copies of themselves are naturally favoured, leading over time to increased refinement and complexity. For instance, why was the five-carbon sugar ribose selected as the backbone sugar in RNA?

This is the question that two researchers at the Scripps Research Institute have tackled. They demonstrated that ribose is far more efficiently phosphorylated than its alternatives, forming the chemical basis of nucleotides—the building blocks of RNA (and later DNA). This efficiency gave ribose a natural advantage, allowing it to "win" the competition against other sugars.

Their findings show that the emergence of ribose was not the result of random chance, but the predictable outcome of the underlying chemistry and physics. The study has been published in the international edition of the journal of the German Chemical Society, Angewandte Chemie.

The work is also summarised in accessible terms in a Scripps Research press 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.

Chemists recreate how RNA might have reproduced for first time | UCL News - UCL – University College London

The problem with having a god who exists merely to fill gaps in human knowledge and understanding — as the god of creationism does — is that science has been steadily shrinking those gaps ever since the scientific method emerged and the Church lost its power to persecute scientists for discovering inconvenient truths. Today, only a few small gaps remain, scattered throughout the body of scientific knowledge —particularly in biology, which holds special interest for creationists.

Creationism persists because there are still people with such a poor understanding of science that they believe the authors of ancient religious texts — written during the Bronze Age, when humanity's knowledge gaps encompassed nearly everything in their small world — had access to some deeper, divine insight. Although what they wrote is often naively simplistic and demonstrably wrong in almost every respect, creationists insist that it somehow surpasses anything modern science has produced in terms of accuracy and reliability.

One of the few remaining gaps where creationists attempt to place their god — the abiogenesis gap — has just shrunk further. Predictably, this will be ignored, dismissed, or misrepresented by creationist frauds who exploit carefully maintained ignorance to preserve their cult followings and income streams.

This discovery by chemists at University College London and the Medical Research Council Laboratory of Molecular Biology reveals how a simple RNA molecule can self-replicate under conditions thought to have existed on prebiotic Earth. Many scientists believe this marks the origin of RNA-based life, which eventually gave rise to the more complex protein- and DNA-based life we see today. A self-replicating RNA molecule, competing for limited resources, will naturally evolve to become more efficient — leaving more copies of itself than rival variants. This is classic Darwinian evolution, operating in a context Darwin himself could scarcely have imagined, knowing nothing of RNA or DNA.

The new research is published open access in Nature Chemistry.

Abiogenesis News - Closing Creationism's Favourite God-Shaped Gap - Still No God(s) Found

How membranes may have brought about the chemistry of life on Earth | Department of Biology

Another hefty spadeful of science has just been shovelled into one of creationism’s favourite god-shaped gaps: the ever-shrinking mystery of abiogenesis. This is the gap that, through the intellectually dishonest tactic of the false dichotomy, creationists claim as evidence for their chosen deity.

Not only is this approach scientifically bankrupt, it also conveniently spares them the bother of providing any evidence or a testable mechanism of their own. For a target audience conditioned to see science as an attempt to disprove their god, the logic goes: if science is wrong—or even just incomplete—then “God did it!” wins by default.

But that dreaded moment for creationists, when science finally closes the gap and, like every other gap in history, finds no need for gods or magic in the explanation, draws ever nearer. The latest discovery bringing us closer comes in the form of new research into the origin and function of membranes—an essential step on the path from chemistry to life.

This particular piece of gap-filling comes from a paper published in PLOS Biology, authored by a team led by Professor Thomas Richards, Professor of Evolutionary Genomics in the Department of Biology at the University of Oxford. The researchers demonstrate that early cell membranes could not only have formed through natural processes, but also had the crucial ability to control what passed through them.

In doing so, they explain what had been something of a mystery and a favourite claim of ID creationists - the chirality of 'living' molecules where all amino acids have the same chirality. Creationists claim this shows the hand of an intelligent designer. This work shows it has a natural explanation.

How life’s building blocks took shape on early Earth: the limits of membraneless polyester protocell formation – ELSI｜EARTH-LIFE SCIENCE INSTITUTE

Creationism’ ever-shrinking little god that sits in the abiogenesis gap, just got smaller with the news that researchers led by PhD student Mahendran Sithamparam of the Space Science Center (ANGKASA), Institute of Climate Change, National University of Malaysia, working at the Earth-Life Science Institute (ELSI) in the Institute of Science, Tokyo, Japan, have shown how primitive protocells could have formed under a wide range of realistic probiotic Earth conditions. The research team included scientists from Taiwan and China.

The research showed that membraneless protocells could have formed by polymerization of alpha-hydroxy acids (αHAs) to form polyester microdroplets, not to be confused with the modern plastic polyester. These polymers were polymers of esters - simple organic compounds which are chemically similar to the monomers that make modern polyester fibres.

Research News - How Life Began on Earth: Modeling Earth's Ancient Atmosphere | Tohoku University Global Site

The fact that living organisms arose on Earth from inorganic sources rather than being made of nothing by magic, is an indisputable fact because there are living organisms on Earth and the chemicals they are composed of all exist on the planet in inorganic minerals and gases. 'Life' contains nothing that 'non-life' doesn't contain.

This much we know, but what we don't yet know and can probably never know with certainty, is precisely how and where that happen. In fact, we don't even know whether it did all start in the same place at the same time because the reason there are two different prokaryote cells - bacteria and archaea - could be because life arose on Earth not once but twice, by two different processes in two different places at two different times.

What we have though is lots of working hypotheses in the process of being validated.

What role would Earth's atmosphere have played in abiogenesis? Earth's early atmosphere was crucial in creating the right conditions for abiogenesis—the process by which life originated from non-living matter. While the exact composition of Earth’s primordial atmosphere is still debated, its unique conditions likely contributed in several essential ways:

1. Provision of Basic Building Blocks
   
   • Earth’s early atmosphere likely contained simple molecules like methane (CH₄), ammonia (NH₃), hydrogen (H₂), carbon dioxide (CO₂), nitrogen (N₂), and water vapor (H₂O). These molecules are rich in carbon, nitrogen, oxygen, and hydrogen—elements that are vital for organic compounds and, ultimately, for life.
   • When exposed to energy sources like ultraviolet (UV) radiation from the Sun or electrical discharges from lightning, these molecules could recombine into more complex organic molecules, such as amino acids and nucleotides, which are the building blocks of proteins and nucleic acids, respectively.
   
   
2. Facilitation of Prebiotic Chemistry
   
   • Experiments like the famous Miller-Urey experiment in 1953 showed that simple gases (methane, ammonia, hydrogen, and water vapor) in an atmosphere subjected to electrical sparks could produce amino acids. This suggests that Earth’s early atmosphere could have been instrumental in initiating chemical reactions that synthesized complex organic molecules.
   • Without a protective ozone layer, the early atmosphere allowed substantial UV radiation to penetrate the Earth’s surface, providing the energy necessary to drive these prebiotic reactions.
   
   
3. Supporting a Reducing Environment
   
   • The presence of reducing gases (such as methane and ammonia) would favor the formation of organic molecules because such conditions prevent the oxidation (and hence destruction) of organic compounds. Oxygen is highly reactive and can break down organic molecules, so the absence of free oxygen in the early atmosphere was likely a key factor that allowed these molecules to accumulate and react.
   • This reducing environment might have helped organic compounds to survive long enough to form stable, self-replicating systems.
   
   
4. Encouraging Geochemical Interactions
   
   • The interaction between the early atmosphere and the oceans, along with geothermal activity like volcanic eruptions and hydrothermal vents, provided a diverse range of chemical environments. In particular, hydrothermal vents may have supplied essential minerals and additional energy sources, further driving complex chemical reactions that are believed to be important in the formation of life.
   • The cycling of materials between the atmosphere and oceans would have contributed to creating localized "hotspots" for prebiotic reactions.
   
   
5. Protection and Concentration Mechanisms
   
   • The atmosphere also played a protective role by preventing the immediate dissipation of important compounds into space. It allowed the concentration of molecules and gases at Earth’s surface, increasing the chances of interactions among the essential precursors to life.
   • Early atmospheres may have helped regulate surface temperatures, preventing extreme fluctuations that would have been hostile to complex chemistry.
   
   
6. Encouraging Self-Organization and Membrane Formation
   
   • Interactions in the early atmosphere could have contributed to the formation of lipid molecules that could aggregate to form primitive cell-like structures or vesicles. These structures would eventually help in containing and protecting reactions necessary for early metabolic pathways.
   • These early "proto-cells" or vesicles would have been necessary to create a boundary for molecular interactions, which is a critical step toward the organization needed for cellular life.

In summary, Earth’s early atmosphere provided a chemically conducive, energetically rich environment that fostered the synthesis and concentration of organic molecules necessary for abiogenesis. This atmosphere also shielded these nascent molecules, allowing them to organize and evolve toward increasingly complex systems, eventually leading to the first living organisms.

One of which is the precise details of the atmosphere on the Early Earth, which is important because it would have had a major impact on the rest of the environment in which life arose. To gain a better understanding of that, a team from Tohoku University, Tokyo University and Hokkaido University, Japan, led by Tatsuya Yoshida have succeeded in modelling that atmosphere, as explained in a Tohoku University press release and published in the journal Astrobiology:

How Life Began on Earth: Modeling Earth's Ancient Atmosphere

The key to unlocking the secrets of distant planets starts right here on Earth. Researchers at Tohoku University, the University of Tokyo, and Hokkaido University have developed a model considering various atmospheric chemical reactions to estimate how the atmosphere - and the first signs of life - evolved on Earth.

Ancient Earth was nothing like our current home. It was a much more hostile place; rich in metallic iron with an atmosphere containing hydrogen and methane.

These molecules contain an important clue to how life was initially formed. When exposed to solar ultraviolet (UV) radiation, they undergo a chemical reaction that produces organics (also known as the "building blocks of life"). Part of these organics were precursors to essential biomolecules, such as amino acids and nucleic acids. However, understanding the role of UV radiation is difficult. Firstly, this type of atmosphere is unstable and likely underwent rapid changes due to atmospheric chemical reactions. Secondly, when UV radiation efficiently breaks down water vapour in the atmosphere and forms oxidative molecules, the precise branching ratio and timescale has not been determined. In order to address these issues, a 1D photochemical model was created to make accurate predictions about what the atmosphere was like on Earth long ago.

The calculation reveals that most hydrogen was lost to space and that hydrocarbons like acetylene (produced from methane) shielded UV radiation. This inhibition of UV radiation significantly reduced the breakdown of water vapour and subsequent oxidation of methane, thus enhancing the production of organics. If the initial amount of methane was equivalent to that of the amount of carbon found on the present-day Earth's surface, organic layers several hundred metres thick could have formed.

There may have been an accumulation of organics that created what was like an enriched soup of important building blocks. That could have been the source from which living things first emerged on Earth.

The model suggests that the atmosphere on ancient Earth was strikingly similar to what we see on current day neighbouring planets: Venus and Mars. However, despite their proximity, Earth evolved into a completely different environment. Researchers are trying to understand what makes Earth so special. As such, this model allows us to deepen our understanding of whether atmospheric evolution and the origin of life on Earth are unique or share common patterns with other planetary systems.

These findings were published in the journal Astrobiology on October 22, 2024.

Abstract
Earth is expected to have acquired a reduced proto-atmosphere enriched in H₂ and CH₄ through the accretion of building blocks that contain metallic Fe and/or the gravitational trapping of surrounding nebula gas. Such an early, wet, reduced atmosphere that covers a proto-ocean would then ultimately evolve toward oxidized chemical compositions through photochemical processes that involve reactions with H₂O-derived oxidant radicals and the selective escape of hydrogen to space. During this time, atmospheric CH₄ could be photochemically reprocessed to generate not only C-bearing oxides but also organics. However, the branching ratio between organic matter formation and oxidation remains unknown despite its significance on the abiotic chemical evolution of early Earth. Here, we show via numerical analyses that UV absorptions by gaseous hydrocarbons such as C₂H₂ and C₃H₄ significantly suppress H₂O photolysis and subsequent CH₄ oxidation during the photochemical evolution of a wet proto-atmosphere enriched in H₂ and CH₄. As a result, nearly half of the initial CH₄ converted to heavier organics along with the deposition of prebiotically essential molecules such as HCN and H₂CO on the surface of a primordial ocean for a geological timescale order of 10–100 Myr. Our results suggest that the accumulation of organics and prebiotically important molecules in the proto-ocean could produce a soup enriched in various organics, which might have eventually led to the emergence of living organisms.

So, by the action if UV radiation from the sun on the inorganic molecules in Earth's early atmosphere for a period of some 10-100 million years, the oceans could have accumulated the basic building blocks for organic organisms to get started, and all th result of chemistry and physics with no magic gods involved at any point.

And, as usual with scientific discoveries, the truth is shown to have little resemblance to the origin myths the parochial Bronze Age pastoralists made up to fill the yawning chasm in their knowledge and understanding of the world around them, with their belief that Earth had only existed for a few thousand years, so were blissfully ignorant of the 99.9975% of its history that occurred before then.
