I find it interesting the DNA sequencing of the so-called native Americans are really a mix of western Eurasian and East Asian.
Columbus was one of the last to discover America. Five hundred years before Columbus (1492) were the discovery by Vikings (led by Leif Eriksson) and before the Vikings, the Chinese.
Canada was discovered in 1534 and Mexico 1511. The Pilgrims landed in 1620.
Did the so-called native American lay claim to Canada, Alaska, Mexico, Guatemala and more as well?
Good question.
I think they got their history off old Hollywood B westerns.
