Somewhat surprising is that the only fully documented submerged megalithic ruins of Ice Age civilizations in the Western Hemisphere are those of the Islands of Bimini on the Bahama Banks, yet when you realize that the empire of Atlantis was thriving to the east both inside the Pillars of Hercules (Gibraltar) and outside too (submerged ruins off Spain), this according to Plato’s description, and that those Bimini cities submerged on the Bahama Banks are where the Gulf Stream flows to Europe, it makes sense that the Bimini shippng outposts were the only major structures built of stone during the nine hundred years after Noah’s Flood, before the Ice Age ended circa 1500 b.c., the Ice Age caused by a warmer ocean.
Then as confirmed by Olmec researchers Michael Xu and Betty Meggers, the Shang dynasty mariners of bronze and iron age China began to arrive in Mesoamerica from across the Pacific circa 1400 b.c., when the drastic sea level rise with the end of the Ice Age and calamitous climate change caused many to seek new land even all the way across the Pacific, and african anthropologist and linguist Clyde Winters proves that Africans were part of the genetic stock of the Olmecs too (google Olmec head statues), so the notion that all ancient settlers of the Americas had trudged across the Bering Land Bridge is certainly rendered ridiculous.
Google search these academics’ names with Olmec History, and you will see why it’s obvious that those anceints had sailed to the Americas by the ancient mapping method according to the very slow wobble rate of the earth’s axis, see http://iceagecivilizations.com/articles/article02.htm. And for the big picture of ancient history after Noah’s Flood, see how it all fits nicely together at http://genesisveracityfoundation.com, the science of the future, old school man. At the foundation website, be sure to refer to section Submerged Ruins Atlantis, to see the real Atlantis according to Plato’s own words, excepting of course his impossble date from egyptian priests for the bronze age metallurgy and global seafaring.
