The archaeological record in Europe is 10x as old as that of North America.
Cool idea, though
They have ignore North Ameica for years because they simply accepted the theory that this country and continent were settled from without. I never accepted that premise and I don’t accept it now. Archaeology in North America has been lacking and still, as of now, we are the undiscovered country. Just watch. There are more than a few surprises awaiting those who accept theories with no basis in fact and the Bering Bridge was one of them.
