Although various ancient traditions refer to a lost antediluvian world, the one that stands out is the tradition in the first chapters of Genesis, because of its geographical detail, its monotheism (which has been shown to predate polytheism) and its historical rather than epic style. These chapters describe a world very different from our own, either because the world really was different or because a later pre-scientific culture speculated about it in error. So what source of information did they draw upon?
As a text, Genesis cannot be older than its reputed author, Moses, about the mid 15th century BC. Some older writings from Mesopotamia, of a chiefly mythic or epic character, contain recognisable elements of the same tradition but broken up, rehashed and mixed in with new material. These suggest that there once was a common, oral, pre-literate tradition from which the author of Genesis and the various authors of the Mesopotamian stories separately drew. A detailed case for this conclusion is made on another page. Here we consider what can be deduced from the Genesis text itself.
In the beginning, rain was not part of the natural order (Gen 2:5). The antediluvian world was watered by moisture which oozed through the soil from a reservoir beneath the land, called the “deep” (2:6, Tsumura 1989). Springs and rivers also got their water from the deep. If oceans had surrounded the land, evaporation would have generated clouds and hence rain, but Genesis does not say there were oceans. It says that the waters were gathered “into one place” (the deep) and were called ‘seas’ (many seas, just as there were many rivers). The seas seem to have been lakes (as in ‘Dead Sea’): enclosed bodies of water supplied by the deep beneath the land. As Psalm 24 says, the land was founded upon seas and rivers. It is pictured as resting on pillars sunk into a single, subterranean ocean, with fish living ‘under the land’ (Deut 4:18). Rainbows were a new phenomenon in the post-Deluge world (Gen 9:13) because rain was a new phenomenon, the ocean from which moisture could evaporate being now at the surface. A different water cycle had come into operation.
Here is evidence that the details of Genesis 1–6 were not the product of speculation based on what Israel inferred about the present world. In any agricultural society, including ancient Palestine, rain was of supreme importance, being the source of the water needed for growing crops and sustaining the pastures that fed their animals. Egypt had the Nile, Mesopotamia the Tigris and Euphrates, the Israelites and the Canaanites had no major rivers other than the Jordan along the eastern edge of the country. Palestine was a land of brooks and springs which drank, irregularly, from the rain of heaven (Deut 11:11). If the rains did not come, the result was drought and famine. It is significant, therefore, that the only mention of rain in Genesis’s description of the first world is the comment that the earth was watered by moisture rising up through the ground rather than rain falling onto the ground. At its formation the land was founded upon waters that were gathered underneath it, called the ‘great deep’, and it was this that sourced the springs and rivers (Gen 7:11).
Far from the Israelites basing their picture of the antediluvian world on their perceptions of the present one, the reverse seems to have been true. They described the present world as if – apart from the addition of rain – it were essentially unchanged since antediluvian times. Jacob promised his son Joseph that he would receive blessings of heaven above and ‘blessings of the deep that couches beneath’. A psalm reminds the Israelites that the rocks which God cleft in the wilderness gave them drink ‘as from the great deep’, and Ezekiel says of a Lebanese cedar that ‘the deep made it grow tall, making its rivers flow round the place where it was planted” (31:4). Fish lived ‘in the water under the land” rather than simply ‘in the sea’.
and all their host by the breath of his mouth.
He gathered the waters of the sea as in a jar;
he put the deeps in storehouses.
When we ask how the psalmist might have known that, the answer must be that he was alluding to a tradition known to everyone. It was part of the nation’s heritage, maintained by song as much as narration (Job 36:24), and in their references to the tradition the psalmists themselves helped to maintain it. So did Solomon when he retold the acts of creation in a section of his proverbs, the only new element being his personification of wisdom, the first thing to be created (Prov 8:22).
The tradition also seems to have been current in countries beyond the confines of Palestine. The inhabitants of the city-state of Ugarit, who spoke a language closely related to Hebrew, had an almost identical word for the deep, denoting the same idea. The Sumerians of Mesopotamia had the same idea but a different word, calling it the Apsu. They visualised the earth as consisting of three levels: the inhabited surface, a middle section where the dead resided, and the Apsu which shut in the ‘sea’ and was the source of all springs, marshes and rivers (Atrahasis, Seely 1997, Horowitz 1998). Most scholars assume that the Canaanites and the Israelites got their picture of the world from the Mesopotamians, by a process of cultural diffusion. However, the cultures of the Near East were far from homogeneous, and it is simpler to suppose that the fundamental elements of Ancient Near East cosmology derived from a common tradition.
The present atmosphere is divided into three temperature-defined layers: the troposphere, where convecting packets of air influence the weather; the stratosphere, where the airflow is mainly horizontal; and the high-temperature thermosphere. Its make-up is 78% nitrogen, 21% oxygen, and 1% other gases, and it thins with altitude.
We know nothing at all about the antediluvian atmosphere. It was probably thicker than now, and it certainly would have had a different composition, for the present mix is the outcome of a continually changing biosphere, weathering reactions and volcanic outgassing. After Creation, oxygen levels were maintained by photosynthesising land plants, after the Cataclysm, by marine bacteria. Free oxygen requires life. Although the assumption has always been that oxygen levels in the Archaean, after the Cataclysm, were negligible, meteorite evidence (Tomkins et al. 2016) shows that the atmosphere was well oxygenated. In the Carboniferous, levels reached 30–35%, promoting unusually large body sizes (e.g. dragonflies with 70 cm wingspans) and widespread fires. In the Triassic the proportion dipped to less than 15%. The atmosphere also needed to have much more carbon dioxide than it does today, to keep the planet warm at a time when heat flow from the interior and heat from the Sun would both have been lower.
Without a magnetic field to protect the Earth, the primeval atmosphere needed to be thick enough to cope with attrition by the solar wind (although the wind may have been weaker). Some of the atmosphere would have been destroyed in the Cataclysm, when fiery asteroids ripped through.
Originally there were no igneous rocks as such, nor rocks derived from them (such as sandstones). Creation theory postulates in the beginning the simplest state that could naturally lead to the present state, the state of minimum entropy. Thus, below the great deep, the planet’s composition would have been homogeneous (not differentiated into crust, mantle and core) and “chondritic”, i.e. it came from the same raw material as the other rocky planets.
At the surface, temperatures were suitable for life. Further down, they would have increased as a function of increasing pressure, along what is called the “adiabatic gradient”. If we assume below the deep a gradient of around 0.3° C per km (similar to the present mantle), the temperature at the centre would have been around 2,000° C, as against an estimated present value of 5,000–6,000° C. With such a gradient the Earth’s interior would have been solid, melting later as a result of thermonuclear fusion. After reaching peak temperatures in the early Archaean, it slowly cooled towards its present state where only the outer core is liquid. As we know from geochemical evidence, the mantle was once hotter and more mobile than now. Nonetheless, even at its present temperature, its long-term behaviour is that of a fluid, convecting and bringing hotter material towards the surface where it melts and occasionally erupts.
Thermonuclear fusion – usually thought to occur only in the centre of stars – was able to occur deep in the Earth’s interior because the speed of light was very much higher. The process generated new elements and isotopes, many of them unstable, and released a vast amount of heat. As the isotopes decayed, they themselves emitted heat. Nuclear fission may also have played a role (Hollenbach & Herndon 2001). The solid interior therefore liquefied, from the centre outwards, and began to differentiate into the chemically distinct regions of inner mantle and core. The overall temperature ceased to rise as (1) continuing decline in the speed of light brought thermonuclear fusion to an end, (2) the rate at which the unstable elements decayed into non-radioactive elements declined, and (3) decay reduced the amount of the radioactive material remaining. The present interior represents a return to the solid state but now partitioned, and still giving out substantially more heat than is generated within. Calculations of how hot the present mantle is may be in error – recent experiments (Sarafian et al. 2017) suggest it is 60° C hotter than previously thought.
The oldest minerals known are tiny crystals of zircon. They do not go back to the beginning but do predate the Cataclysm. They show that melting and recrystallisation was taking place in the presence of water, and that the interior was hot enough for granites to form. The mention of gold, iron, copper and quartz (onyx stones) in Genesis also implies magmatic processes, though we cannot infer that metal ores existed right from the beginning. Probably a long period elapsed before the minerals rose to the surface in saturated fluids.
Volcanic eruptions are likely to have become more frequent as time went on. With the heat of the interior increasing, thermal pressure under the land also began to build up. As sometimes happens before a volcanic eruption, the springs which watered the land may have dried up under the pressure (as related in Atrahasis). Eventually, the springs exploded and the lithosphere disintegrated. Within 40 days even the highest mountains were shattered and submerged, hot magma now rising over their underwater ruins.
Estimates of how much water remains locked up in mantle minerals are steadily improving. Not that long ago it used to be thought there was almost none. Now, as a result of analysing diamonds from deep in the mantle, the best estimate is at least as much as in the oceans at the surface, mostly stored in the transition zone between the upper and lower mantle (Keppler 2014). Some water enters the interior through subduction of wet oceanic plates and is then recycled to the surface through outgassing along volcanic arcs. The peoples of the Ancient Near East were not wrong in supposing that the great deep still existed in their day.
Earth’s lithosphere is appreciably less rigid, and wetter, than those of other rocky planets (Araki et al. 2009). This is consistent with the Earth’s being the only planet at creation to have hosted water. After the Cataclysm the water either escaped to the surface or became mixed with the upper mantle. The uppermost mantle appears to be saturated with water (Bolfan-Casanova 2005). By lowering its melting temperature, water – like carbon dioxide – weakens the lithosphere, and it is this weakness that, from the Archaean onwards, facilitated plate tectonics. The melting of crust above the subducting plates led to the formation of granites and contributed to the foundation of new continents.
The light that originally generated cycles of day and night came principally from a source beyond the solar system, daylight having been created three days before the Sun. What was that light? Modern astronomy has brought us to the point where we can give a definite answer. Looking back in time to the farthest reaches of the universe, we find that in the beginning there were only quasars, not stars in the modern sense. These massive ultra-bright objects were as bright as entire present-day galaxies, and it is from them that galaxies arose, as quasars ejected voluminous streams of plasma and the plasma condensed into stars. The clouds of dust and gas permeating the arms of galaxies are the sparse remains, after star formation, of what was ejected from the centre.
Since our own Milky Way is also a galaxy, it too must have originated in this manner. In the beginning there was only a quasar, the source of the light created on the first day. Although it has long since shed most of its mass, a ‘black hole’ containing its collapsed remains still marks the spot. In this respect the Milky Way is unusual. Its central black hole is non-luminous, whereas the black holes at the centre of most galaxies, called ‘active galactic nuclei’, are so massive that the matter falling into them emits an enormous blaze of light.
The Sun can be inferred to have started as a concentrated globe of pure hydrogen, because pure hydrogen is the simplest chemical state, and a cloud of pure hydrogen gas will not, of itself, collapse into a star. It shone from the fourth day onward and gave additional light. Over time the rate at which it fused hydrogen into helium increased, owing to the increase in heat arising from its gravitational contraction, helium being denser than hydrogen. Its initial heat output was probably no more than 70% of its present output, and if it had been the only source of heat the Earth’s oceans would have frozen over. This is cosmology’s ‘faint young Sun problem’, since geological evidence shows that the young Earth was actually warmer than today. In our view the light deficiency was made up by the Milky Way’s primordial quasar, while terrestrial heat loss was mitigated by higher levels of greenhouse gases.
The Sun’s present-day helium is thus the product of the thermonuclear fusion of hydrogen atoms. Its carbon, nitrogen and oxygen, in turn, are fusion products of helium. Its other elements derive from asteroidal debris.
The higher level of radioactivity was due to higher proportions of the decaying parent isotopes and a higher velocity of light (c), to which rates of radioactive decay are linked. The decline in c was a change which affected the entire universe and must itself have had a physical cause, possibly to do with the energy of the so-called vacuum. The postulated decline in c may tie in with the problems that the hypotheses of ‘dark energy’ and ‘dark matter’ seek to solve in standard cosmology.
The Moon was created on the fourth day of Creation. Amongst those looking for a natural explanation the leading idea for the past three decades has been ‘the Giant Impact Hypothesis’ – that the Moon spun off from a giant collision between Earth and another planet that vaporised in the collision. Because the greater part of the Moon would have originated from the impacting body, and all planets differ from each other in isotopic composition, the hypothesis predicts that the Earth and the Moon will also differ. In fact, the isotopic signatures of the Earth and the Moon are remarkably similar. The hypothesis is in crisis, says Linda Elkins-Tanton (Nature Geoscience, Dec. 2013), and ‘creative thinkers’ are required to make it plausible. The Moon’s ongoing resistance to natural explanations is evidence that it did not have a natural origin, though of course scientists will never give up looking and hoping for one. The latest suggestion is that the Moon arose from a succession of smaller collisions (Nature Geoscience, Jan. 2017).
The idea of a planet exploding quite close to the Earth is not necessarily far fetched. In addition to the eruption of the great deep, at least one other violent event rocked the Earth at this time, the explosion of a planet of which remnants, in the form of asteroids, still exist. The explosion was close enough for fragments to crash through ‘the windows of the heavens’ (Gen. 6:11) and pulverise the land. On the Moon, craters up to thousands of kilometres across have left abiding testimony of the cataclysm. At the same time the water vapour that had gradually spread from the edge of the solar system and collected in the Earth’s outer atmosphere collapsed under the onslaught and added to the flooding. Again, the Moon still retains traces of that primordial water.
The surface of the Moon was originally not cratered. Nor was the surface blotched by the vast plains of basalt (maria) that erupted in the wake of the impacts. Its surface topography, from volcanic “seas” to crater-rimming mountains, is entirely the effect of later bombardments.
The Moon’s upper crust is mostly composed of anorthosite, a white igneous rock rich in feldspar. It is igneous in the sense that its mineralogy and texture is that of a rock crystallising out of a chemically more primitive magma. The solid state implies an earlier molten state because magma will cool and crystallise by itself to produce the rock and creator input is not required. Thus cosmologists are not being unreasonable in deducing that the anorthosite crust of the Moon crystallised from a ‘magma ocean’. This low-density iron-depleted rock type is exactly what one would expect at the surface if the interior melted.
So the Moon must have been resurfaced in the period before the cataclysm, as a result of the heat released by thermonuclear fusion and the decay of the radioactive elements produced by the fusion. None of the rocks sampled by the Apollo missions go back to the Creation. Magmatism remade the lunar crust, the cooling of which was accelerated by water from outer space. Not long thereafter bombardment by asteroids shattered its surface, blanketing it with dust and ashes kilometres deep. The indistinct rims of the oldest craters show that the crust was still plastic when the first asteroids fell.
Another piece of evidence that suggests we are dealing with an authentic tradition is the place names. Because the old landmass was totally destroyed, a map of the world would have looked nothing like a modern map. The only remains from pre-Flood geography are names (e.g. ‘Tigris’, ‘Euphrates’), referring to features that cannot be correlated with their present-day counterparts.
The first place name in Genesis is Eden (meaning ‘delight’ in Hebrew). God planted for himself a garden there. Although it is subsequently mentioned several times (e.g. Isa 51:3, Ezek 31:9), as a contemporary place it is rarely mentioned (chiefly Isa 37:12 and Ezek 27:23), and because of its obscurity its location has never been convincingly identified. The Eden that was a byword for a land of fruitfulness was known only from tradition; it was a different Eden, belonging to a world that no longer existed.
The toponyms associated with the original Eden are also irreconcilable with the geography of the Near East. Genesis tells us that a river flowed up from underground to water the garden there and then divided into four. This ought to be a clue to its location if the world in which Eden existed itself still existed, for the rivers are named and two of the names are well known: Tigris and Euphrates. These rivers run through Iraq, with headwaters in eastern Turkey, and there have been attempts (e.g. Rohl 1998) to identify the other two, Pishon and Gihon. These ought to be at least as impressive. However, there is no single river from which the Tigris, Euphrates and two other rivers branch off.
Pishon, moreover, was said to flow ’round the whole land of Havilah’. Havilah is mentioned in Genesis 10:7, 10:29, 25:18 and I Samuel 15:7, contexts which show that it must have lain in southern Arabia. Since no river connects Turkey with Arabia, it seems safe to conclude that the primeval Havilah was a different country from the one later known by that name.
Similar arguments may be made in relation to the lands of Cush (Gen 2:13), Assyria (2:14) and Nod (4:16). In Old Testament times Cush was the eponymous name for Ethiopia (Cush being the ‘son’ of Ham whose descendants settled that part of Africa after the Deluge), Assyria was the northern part of Mesopotamia, through which, not east of which, the Tigris flowed, and Nod, to judge from the lack of its mention in any other ancient text, had no post-Flood counterpart at all, perhaps unsurprisingly, seeing it was associated with an exiled fratricide.
The apparent persistence of topographical names from the antediluvian world is therefore a red herring. In contrast to those who claim to have located the original Eden, most scholars conclude from the impossibility of doing so that the original Eden was a myth. However, the most likely explanation is that the names were re-assigned to the Near East by migrants who knew about such places from the traditions of their forefathers and wished to simulate continuity with that lost world, much as colonists arriving in North America from England sought to recreate what they called the old world with names such as Portsmouth, Cambridge and New York. The land of well-watered plains, abundant game, cereals, date-palms, and pulses evoked hopes that it might become a new Eden, and the two main rivers were named accordingly. Some of Mesopotamia’s most ancient cities were named after antediluvian patriarchs, such as Eridu (Eriduk), after Irad (Gen 4:18), and Uruk (Unuk), after Enoch, Irad’s father. When, around the end of the Jemdet Nasr period, the Euphrates breached its banks and devastated a number of the cities in severe flooding, people likened the disaster to the primeval deluge, until eventually poets were describing it in the same terms, even to the extent of casting one of their kings in the role of Noah. This purely Mesopotamian flood was, however, a different and much later event.
As a clue to the landing place of the Ark, the reference to ‘the mountains of Ararat’ (plural) is also a red herring. Although located in the post-Deluge world (the rim of an impact crater?), the mountains were as much part of the Creation-Deluge story as the Tigris and Euphrates, and were therefore equally susceptible to the process of toponym-transfer. The nearest mountains to Mesopotamia were the Zagros range. A country or city in the Zagros called Aratta features in several Sumerian texts of the 3rd millennium BC (in Sumerian the name actually means ‘mountain’). According to the later Gilgamesh epic, which conflated the Deluge and the Mesopotamian flood, the Ark came aground on Mount ‘Nimush’, possibly Pir Omar Gudrun, near Kirkuk. Jeremiah (51:27) mentions that a kingdom called Ararat within reach of Assyria (Isa 37:38) formed an alliance with the kings of Minni and Ashkenaz. The context suggests an identification with the similarly named kingdom of Urartu, in Armenia. Although this was a different location, the appropriate conclusion may simply be that the toponym had been transferred again: by the 7th century BC some new region had claimed the distinction. The association with Turkey’s Mount Ararat (Agri Dagh), a volcano which formed in the Late Cenozoic, seems no older than the 11th century AD.
As with primeval Eden, the quest for the remains of Noah’s Ark on the basis that it might exist anywhere in the Near East is the quest for a chimaera.
