Actually evidence suggests that the "white" man was there before the indians. If you watched a 60 minutes episode, where a very old "kaukasian" body had been found in a riverbed ( military area today). Evidence suggested that the "white" man and ancestors had been living in the area for longer than any indian would have been able too.Funny thing, cause of death= looked like indian arrow head, but the story ends here - all of a sudden the military had to build a superstructure on top of the exact same spot as the body had been found. How convenient?
