Whats really funny is...The History Channel had to mix the truth in with other theory, and if you pay actual attention to the video, they'll say that the other theories are just myths and speculation.
Well, theres more than just those things in the video that were left..
One thing I heard in the video narration was him using the religious chronological term "A.D." and not the more scientific "B.P."
Pretty much before about 30 years ago all Anthropology was based on Enthnography, mixed with that Political Archaeological mind set..."must stay inside the bounds" type thing.
Heres the clip that was missing - someone deleted the History channel clip - The History channel shows title is "Who really discovered America" This starts from part 3 but there are other parts. So if this clip goes missing, look up the titles.
