Now becoming well-known to mainstream scientists and historians is the fact that a catastrophic climate change forever altered the geography and environment of the ancient mediterranean region circa 1500 B.C., leaving megalithic and brick bronze age ruins of once thriving cultures left in windswept deserts, with much evidence that those ancient sites were green with vegetation because of plenty of rainfall, which enabled those ancients to build and thrive in areas which turned into deserts within centuries, beginning circa 1500 B.C., when the Ice Age ended.
New Ager types, archaeologists, and authors, David Hatcher Childress and Graham Hancock, have done much good work establishing that many ancient megalithic cities were submerged by the sea when the Ice Age ended, but they’re hung-up on the mainstream scientists’ date for the end of the Ice Age at circa 10000 B.C. (or within a few thousand years of that), and so, are forced to say that megalithic building had been ongoing at least five thousand years longer than mainstream archaeologists are rightly proponing, the megalithic and brick building of cities having begun circa 2500 B.C. with the foundation of the great ancient civilizations such as of Canaan, Greece, and Egypt, ruins of which are now submerged on the shallow seafloor from the time of the end of the Ice Age, when Atlantis too went under.
You’d think those two (Hancock and Childress), along with Franck Goddio (who photographs the submerged ruins of Menouthis and Heraklion off the coast of Alexandria, Egypt), would read the Ipuwer Papyrus, recorded circa 1400 B.C., which eloquently describes the despair and anarchy which reigned in Egypt, actually at the time of the Exodus of the Jews, with drought, famine, and plagues, when the climate and way of life in North Africa forever changed, leaving many ruins now in the middle of desert sands, to understand that was really the end of the Ice Age, when the submerged ruins, whose date of submergence is confusing to them, were consumed by the sea with the prodigious icepack melt in the extreme latitudes, and with the greatly dissipating cloudcover at that time, the rainfall drastically decreased in the middle latitudes.
