Research since the 1970s suggests that there were three global super-floods: 15,000 to 14,000 years ago; 12,000 to 11,000 years ago; and 8,000 to 7,000 years ago. The second period ties in with the date Plato ascribed in the Timaeus and Critias to the destruction by earthquakes and flooding of Atlantis, and with the Tamil myth of the submerging of the fabled land of Kumari Kandam. There is also strong evidence that nearly half the total melt water released at the end of the last Ice Age was concentrated into these three relatively short periods. Such events would have had a momentous impact on the human inhabitants at that time, leaving a marked impression on oral tradition, the original transmitter of all ancient myths
Allan and Delair, like the main Catastrophist Theorists before them, understand that the massive casualties among the world's fauna did not occur due to movements of glaciers and ice sheets over millions of years. In the tradition of Beaumont and Velikovsky they review the extinction events that appear to have occurred over twelve millennia BC and that are also recorded in the world's myths and legends.
The time allegedly occupied by the glacial and interglacial episodes of conventional Pleistocene chronology was actually non-existent
...it is astonishing that such an unscientific explanation ever came to be formulated, yet in a short time both it and the concept of immense thick ice-sheets descending from a hypothetical northern mountain system…was enthusiastically embraced...as virtually established fact
What! No Ice Age that came and went, spreading over hundreds of thousands of years as all good geologists proclaim? No smothering ice sheets that enveloped the British Isles and much of the northern parts of the Continent, changed the climate to Arctic conditions…No. Nothing of the sort. There was admittedly a tremendous convulsion of nature, that had the most direful effect upon the inhabitants of Scandinavia, the British Isles, and those in Northern Asia. It resulted in giving us, it is true, bitter cold, tremendous floods, and cruel dampness. That it affected the climate in the north adversely and permanently cannot be denied. It did other things as well. But no Ice Age
…no satisfactory theory has yet been proposed that actually explains what caused the ‘Ice Age’ in the first place. There appear to be no terrestrial conditions, as we know them, capable of producing the heat necessary to evaporate vast quantities of water to form continental-sized ice-sheets
