Connecting the great universal myths of cataclysm, is it possible that
such coincidences that cannot be coincidences, and accidents that cannot
be accidents, could denote the global influence of an ancient, though as
yet unidentified, guiding hand? If so, could it be that same hand, during
and after the last Ice Age, which drew the series of highly accurate and
technically advanced world maps reviewed in Part I? And might not that
same hand have left its ghostly fingerprints on another body of universal
myths? those concerning the death and resurrection of gods, and great
trees around which the earth and heavens turn, and whirlpools, and
churns, and drills, and other similar revolving, grinding contrivances?

[The Edfu Building Texts in Egypt] take us back to a very remote period called the 'Early Primeval Age of the Gods' — and these gods, it transpires, were not originally Egyptian, but lived on a sacred island, the 'Homeland of the Primeval Ones,' and in the midst of a great ocean. Then, at some unspecified time in the past, an immense cataclysm shook the earth and a flood poured over this island, where 'the earliest mansions of the gods' had been founded, destroying it utterly, submerging all its holy places, and killing most of its divine inhabitants. Some survived, however, and we are told that this remnant set sail in their ships (for the texts leave us in no doubt that these 'gods' of the early primeval age were navigators) to 'wander' the world. Their purpose in doing so was nothing less than to re-create and revive the essence of their lost homeland, to bring about, in short: 'The resurrection of the former world of the gods ... The re-creation of a destroyed world.'

The takeaway is that the texts invite us to consider the possibility that the survivors of a lost civilization, thought of as 'gods' but manifestly human, set about 'wandering' the world in the aftermath of an extinction-level global cataclysm. By happenstance it was primarily hunter-gatherer populations, the peoples of the mountains, jungles, and deserts — 'the unlettered and the uncultured,' as Plato so eloquently put it in his account of the end of Atlantis — who had been 'spared the scourge of the deluge.' Settling among them, the wanderers entertained the desperate hope that their high civilization could be restarted, or that at least something of its knowledge, wisdom, and spiritual ideas could be passed on so that mankind in the post-cataclysmic world would not be compelled to 'begin again like children, in complete ignorance of what happened in early times.
