Ancient history like the question of "When did humans arrive in North America" seemed like a big yawner when I was in High School and College. But I since realized the importance of this question.
e.g. There's the quip that if you can control what people think about the past, you can control the future. Suppose human history contains much more than what we were told? And that by hiding the truth of human history, the ignorance of the people leads them to being more controllable?
But that's kind of far-fetched isn't it? Or is it? Is our current civilization, spanning back to the Babylonians, the only time when creatures on this planet were intelligent tool-using beings? Or was there a previous period of history when the creatures on the planet were just as "advanced" as we are now?
Footprints of 'first Americans' (By Paul Rincon, BBC News science reporter)
This story has nothing to do with the questions I raised above, except that it is documented proof (still to be validated, however) of human arrival well earlier than the currently prevailing theory. The prevailing theory is arrival across a land bridge in Siberia 11,000 years ago. However the article discusses a discovery of a footprint next to an old lakebed in Mexico that predates that by 30,000 years. Hmmm....
