Beginning at around 1500 B.C., the ancient world was turned upside down, mass migrations by many ancient people groups are known to have begun to occur around that time: the migration of the Aryans (Iran) from Central Asia into India, the Exodus of the Jews out of Egypt, the migration of Assyrians and Ashkenazi from the Black Sea region into Germany, and the invasion of the eastern Mediterranean by the “Mysterious Sea People,” who sailed in thousands of Bronze Age ships from the west, plainly from Atlantis, most of whose coastal trade empire vanished beneath the waves at the end of the Ice Age.
And with the end of the Ice Age, the sea level rose to also infill the inland Old Black Sea lake, as the ocean rose up the river valley which is now the Dardanelles (Dardanus), to pour into the basin of the Old Black Sea, connecting it to the world ocean, and so, many Assyrians and Ashkenazi (as well as Scythians and Cimmerians) lost land with the infilling, and with the drastic drying out of their environment there beginning at that time with the end of the Ice Age, they began to migrate west to Germany, which was losing it’s Ice Age icepack, rapidly, beginning circa 1500 B.C.
Notice the dearth of 2000 B.C. vintage megalithic dolmens, stone circles, fortresses, and temples, in northern Europe, whereas they are plentious in southern Europe, this is because the Ice Age icepack covered much of northern Europe until 1500 B.C., so the great cyclopean megalithic builders concentrated in the Mediterranean region. (The Greeks of Plato’s time looked at the gigantic hewn stone building blocks, fitted tightly together, such as at the citadel of Mycenae, and thought that the giant cyclops people must have built them.)
And huge waves of Aryans moved down from the region of Iran, Elamites and Assyrians (Azuras) among them, because the Ice Age end was drying out the Middle East, making that land sustaining for far fewer people, and so, they headed south, to the land of Rama in India, which was also drying out, as the Rama Empire there was collapsing, as the sea level rose to consume their coastal cities, such as Old Dwarka, with the end of the Ice Age.
Egypt was also in a panic at that time. The sea level was rising to consume their port cities of Menouthis and Herakleion, which may have actually been Canaanite (Phoenician) cities, volacanos such as Santorini were going off, blackening the sky with soot, the land was drying out, with the Nile dropping, and pestilence, starvation, and anarchy, as described in the Ipuwer Papyrus. This is when the Exodus of the Jews out of Egypt occurred, and shortly thereafter, the “mysterious” Sea Peoples assaulted the coast of Egypt with huge fleets of ships, and Libyans were migrating east to Egypt, as the lakes and streams of the Ice Age Sahara were drying out.
All this because the oceans had cooled to end the Ice Age. The oceans must have been warmer for evaporation to fuel the cloud-cover for the Ice Age, and necessarily geothermally heated from below, by the fountains of the deep of Noah’s Flood, because atmospheric heating of the oceans would have been reversed by the negative feedback mechanism of denser cloud-cover therefrom. Warmer oceans for the Ice Age is seemingly a paradox, but it’s merely Hydrology 101, necessarily geothermally heated.
