Hey Skinster, isn't it ironic that the period of mass migrations in the ancient world occurred circa 1500 B.C., when the Exodus occurred, when the Aryans came to India, when the Goths, Vandals, and Assyrians began to move into Europe, when the "Old and Middle" Kingdoms of Egypt collapsed (see the Ipuwer Papyrus), and when the Sea Peoples began to invade Egypt, why did this all happen at once?
And don't forget, the Kingdoms of Rama and Kumari Kandam of India were submerged at this time, along with many others, because the sea level rose several hundred feet, why of course, because that is when the Ice Age ended.
Please cite the primary literature for your claims. There have been many "mass migrations" throughout the history and prehistory of man.
Moreover, sea levels had leveled off by around 4000 BCE, by the end of the Ubaid period. Indeed, they actually
receded somewhat by 3800 -3200 BCE during the Uruk period. The "ice age ended," for all intents and purposes, by around 4,000 BCE (McClure 1978). The peak of the Würm glaciation was around 18,000-16,000 BCE, from that point to 4000 BCE the glaciers retreated and conditions changed from generally dry and cold to wet and warm (Fairbridge 1961; Kassler 1973; McClure 1978).
Your spurious claims have the appearance of pseudoscience, as they are unfounded, unreferenced, and unreliable. But we await your citations.
