Certain tribes claim that their peoples have always lived exactly where they were when found by the white man. This is not true, as many migrations have occurred. Notably, the Sioux uses to live around the Great Lakes. They didn't start moving onto the Great Plains until the late 18th century.
The claim they make is in rejecting the "white man's theory" that they came across the Bering land bridge some 10,000+ years ago. They claim they have literally "always" lived here. And purportedly scientific books treat their claims with great respect.
My only question is why idiotic unscientific tribal beliefs are treated respectfully when they are those of the Sioux tribe, but not when they are those of the fundamentalist tribe?
