Updated periodically as new science emerges
For this is what the Lord says—
he who created the heavens,
he is God; he who fashioned and made the earth,
he founded it; he did not create it to be empty,
but formed it to be inhabited— he says:
“I am the Lord, and there is no other.
Isaiah 45: 18
Just a few short decades ago, the Earth was considered to be an ordinary planet, orbiting an ordinary star, lost in a vast galaxy of other stars, amid myriad other galaxies populating the Cosmos. Mindless processes produced the first living organisms, we were told, which slowly evolved over the eons to produce creatures like us1. This secular myth was accepted hook line and sinker by the uneducated masses after its promotion by God-denying ‘high priests’, including the late Arthur C. Clarke, Carl Sagan and Richard Dawkins, and mindlessly parroted by a generation of science journalists unwilling to dig any deeper. Yet, with the exponential rise of human knowledge, this worldview is being radically over-turned by an avalanche of new science, that paints an entirely different picture of our world: one in which its exceptional properties for supporting a long-lived biosphere for the express benefit of humanity in particular, is coming to the fore; where life itself ‘terraformed’ the Earth under Divine instruction.
An Anomalous Solar System
Many lines of evidence show that the Earth is old; 4.543 billion years with an uncertainty of just one per cent. But the circumstances under which our planetary system was shaped were very unusual. Formed from the gravitational collapse of a vast cloud of gas and dust, the proto-solar system condensed into a relatively thin disk with the neonatal Sun at its center. The inventory of elements endowed to the solar system might have turned out to be much like any other were it not for the presence of at least two relatively close-by supernova events2 which helped eject it from a nursery of other stars, but which also enriched the primordial solar system with relatively large quantities of heat-generating radioactive elements such as aluminum 26, thorium and uranium3. The aluminum 26, with its short half-life of 730,000 years, provided enough thermal energy to remove excess levels of volatiles including water, carbon monoxide and carbon dioxide which would have scuppered the future emergence of living creatures on our world. In contrast, the very dense and long-lived radioactive elements like uranium and thorium sank to the center of the primordial earth, where their prodigious heat has kept the planet in a geologically active state over billions of years.
The most recent research on star formation shows that the Sun is far from being an average star4. Indeed that distinction goes to stars with masses roughly 50 per cent less massive than the Sun, with luminosities only 5 per cent as bright and surface temperatures of 3600K4, comprising some 80 per cent of all the stars in the Universe. Many more are smaller L dwarfs that are unable to fuse hydrogen in their cores, or larger stars than the Sun that have much shorter lifespans. In the words of the University of Rochester astrophysicist Adam Frank;
“Please stop calling our Sun an “average star. It is philosophically dubious and astronomically incorrect.4 ”
The Moon-forming event, which is thought to have occurred about 100 million years after the neonatal Earth formed5, in a highly improbable, oblique collision with a Mars-sized object, helped remove still more volatiles from the primordial Earth, allowing it to eventually form relatively shallow oceans where the continental land-masses could eventually emerge from the sea floor. The debris from this cataclysmic event formed a relatively large Moon in close proximity to the Earth, helping to stabilize its orbital inclination and over time, to slow down the rotation rate of our planet from just 5 hours shortly after the Moon’s formation, to its present leisurely rotation period of 24 hours.
For the first few hundred million years after its formation, the Earth would have looked black and golden from the vantage of outer space, from the vast amounts of solidified magna cooling on its surface as well as the prodigious levels of volcanic activity spewing out hot lava from the planet’s interior. Frequent collision events with smaller space debris like asteroids would also have exacerbated these hellish conditions, but eventually the prodigious levels of water vapor outgassed from its interior would have transformed our lava dominated planet into a blue water world still devoid of continental landmasses.5 But just as soon as the Earth cooled down enough to enable liquid water to flow on its surface, life appeared.
Life Terraforms the Planet
The standard evolutionary story is that life began as simple organisms and gradually progressed to more complex forms with the slow march of time, but the best scientific evidence now suggests that this life was already complex and biochemically sophisticated. This is based on isotopic evidence6,7 from the analysis of ratios of carbon and sulfur isotopes in sedimentary rocks laid down over 3.5 billion years ago. Since these biochemical processes have an absolute requirement for highly complex protein enzymes to have been present, it completely eludes an evolutionary explanation. Then why did our Creator choose to begin Earth’s life story with microbes? The answer has less to do with evolution than it has with chemical sophistication. The simple answer is that microbes are, by some considerable margin, the hardiest creatures ever to have lived on our planet.
Microbes are the die-hards of the living world, being capable of surviving in very hot and cold temperatures, high and low pH environments, and can even thrive in a cocktail of toxic chemicals and radioactive environments. Once the planet cooled enough to allow the first microbes to survive, they were set to work removing a plethora of poisonous substances from the primordial Earth. In these early times, the Earth’s surface would have had large amounts of so-called vital poisons, substances that are required in small amounts for more complex life to thrive, but in higher concentrations, can prove lethal; substances like iron, copper, zinc, molybdenum, arsenic, boron, selenium and iodine, to name but a few. In their soluble forms such vital poisons would have stunted any new life forms coming on the scene but in chemically transforming these elements8 into insoluble ores and minerals, microbes not only removed such vital poisons from the Earth’s water environments but also formed large deposits of the valuable minerals that are now mined for their use in high technology devices. This also makes sense from a creation point of view, as more complex organisms are far more sensitive to these toxins than microbes are. One other benefit that life brought to the Earth is that it greatly enriched the planet’s mineral and gemstone tally. According to Dr. Robert Hazen, a world-leading mineralogist, Earth has the greatest diversity of mineral species of any body in the Solar System.5 Over 4,600 mineral species have been identified on Earth. In contrast, Mars probably has about 500 and Venus about 1,000 at the most. What’s more, Hazen discovered that life processes formed about two-thirds of Earth’s mineral species5.
Recent oxygen isotope evidence shows that ongoing plate tectonic activity produced nearly all the continental landmasses by about 2.5 billion years ago.9 The fact that just 29 per cent of the planet’s surface area is covered by dry land appears to be highly fine-tuned. Greater land surface areas would induce too little precipitation in the interior of those ancient continents, preventing life from gaining a hold in these places. On the other hand, land areas significantly less than 29 per cent would not be able to re-cycle enough valuable nutrients between the land, the sea and the atmosphere to maintain a healthy biosphere.
The earliest lifeforms extracted energy from these minerals without the need for molecular oxygen, but the introduction of photosynthetic microbes radically transformed the early biosphere, paving the way for the introduction of advanced lifeforms. One way to get a handle on how early oxygenic photosynthesis occurred on Earth is to study so-called Banded Iron Formations (BIFs)comprised of iron rich clays containing magnetite and hematite. The early oceans had high concentrations of soluble iron, but when it reacts with oxygen, it forms an insoluble rust-like substance that serves as iron ore today.
Such studies reveal that BIFs were first laid down about 3.0 billion years ago, continuing up to about 1.8 billion years ago.10 This coincides with the microfossil record of life, which shows that oxygen-dependent complex cellular life (the so-called Eukaryotes) made its first appearance around 2 billion years ago.11The rise in atmospheric oxygen also created the ozone layer, which protected future life on land from the damaging effects of ultraviolet radiation from the Sun. The emergence of oxygen-generating photosynthesis had other effects that are not immediately obvious. When the Sun was born, it was about 30 per cent less luminous than it is today, but as it aged, its luminosity increased with the result that the amount of thermal energy received by the planet also increased. Photosynthetic organisms removed great amounts of greenhouse gases from the atmosphere by absorbing carbon dioxide and generating oxygen which reacted rapidly with another greenhouse gas, methane. In so doing, photosynthetic organisms served to counteract the tendency of the aging Sun to overheat the planet.12 The remains of these and other unicellular creatures settled to the bottom of the oceans where they formed vast sediments that were compressed over time to produce natural gas and oil reserves so important to human civilization today.
After a long cooling phase coinciding with the formation of the supercontinent, Rhodinia5, signs of the first large(macroscopic) multicellular lifeforms appeared about 600 million years ago in an event known to palaeontologists as the Avalon Explosion, where scientists have uncovered the first evidence of simple animal lifeforms. It is unclear however whether these bizarre creatures were animals or plants but what is clear is that in the space of a short 410,000 year period starting around 541 million years ago, 80 per cent of all existing animal forms appeared in the fossil record, with no credible evolutionary antecedents3,22. Paleontologists studying the so-called Cambrian Explosion have found no transitional forms in layers immediately pre-dating this period in Earth history. Moreover, the land was being prepared for the arrival of vascular plants by fungi who began breaking down rocks into soil as early as about 1000 million years ago14. It is difficult to conceive how any blind process like Darwinian evolution could produce such stunning biological complexity and diversity in such a short space of time without any foresight.
In recent times, a greater appreciation of the interplay between life and plate tectonics has been appreciated. Without plate tectonics, our planet wouldn’t have a climate stable enough to support life over billions of years of time. That’s because plate tectonics takes center stage as a planetary thermostat in a process called the “carbonate-silicate” cycle.13 Carbon dioxide in the atmosphere dissolves in rainwater to form carbonic acid, which dissolves silicate rocks. The by-products of this erosion, or “weathering,” are conveyed to the oceans where they are ingested by organisms—such as tiny planktonic foraminifera—and incorporated into limestone (calcium carbonate) shells. When those creatures die, they fall to the bottom of the ocean and pile up as sediments, creating new raw materials used by humanity. The introduction of life on planet Earth also increases the amount of water subducted into the mantle, where it functions as a kind of lubricant, facilitating motions between plates. It also lowers the melting point in the mantle, which leads to more volcanism and therefore more continent building. So, without life speeding up the weathering at the surface as well as the sedimentation rate on the sea floor, the fraction of the surface covered by continents would be far smaller.
Plate tectonics has other, hitherto unforeseen consequences for the maintenance of the Earth’s strong magnetic field. By accelerating the transfer of heat to the surface, plate tectonics induces convection in the liquid iron outer core of our planet. What’s more, it’s the dynamic outer core that generates our planet’s magnetic field, which protects Earth’s atmosphere and oceans from excessive erosion and desiccation from the solar wind as well as all surface life from dangerous cosmic rays.
The fossil record attests to several mass extinction events that occurred over the long history of our planet.14 Research has shown that these devastating events are followed by equally spectacular mass speciation events, uncannily similar to the scenarios described in Psalm 104. According to Christian astronomer, Dr. Hugh Ross, these events proved crucial for maximizing both the quantity and longevity of Earth’s life.15 By ensuring that the right quantities and kinds of life are present at the right times, our Creator employed these organisms to remove the just-right quantities of greenhouse gases from Earth’s atmosphere so as to compensate for the Sun’s increasing brightness. According to Ross, one would expect God to intervene periodically to remove life no longer appropriate for compensating for a brightening Sun and then replace it with life that is more efficient at doing so. Finally, in the last few hundred million years, vast deposits of coal and oil were produced from the remains of plant life that flourished on land during the Carboniferous and Permian (360 to 250 million years ago) periods, which was necessary for the launch of the industrial revolution.
Seen in the light of these new scientific discoveries, it is apparent that the Earth is a highly fine-tuned planet that has sustained a very stable environment over 4 billion years for the flourishing of life. And that same life transformed our world beyond recognition to make it ideal for humans to thrive in. This consensus is now being expressed by other scientists, who have noted Earth’s amazing properties. Influential books like Donald Brownlee and Peter Ward’s Rare Earth18: why complex life is are in the Universe, David Waltham’s Lucky Planet19, John Gribbin’s Alone in the Universe20 as well as Privileged Planet21by Guillermo Gonzalez and Jay Richards, all seem to be singing from the same hymn sheet. Far from being a humdrum planet orbiting an ordinary star, the Earth was designed by a mind vastly more advanced than our own. And I give God all the glory!
