I haven't seen the new documentary, but I read one of Hancock's books years ago. His book Underworld, which is about how evidence of ancient civilizations is underwater as the coastline has changed dramatically over the last few thousands of years. I think he draws way too many conclusions from way too little evidence, but that premise itself has always struck me as incredibly plausible. The issue is that a lot of the evidence is underwater now, and therefore hard to get to. But that doesn't really mean we shouldn't be looking for it though, right? Otherwise we're like the drunk looking for his keys under the street light because its easier, not because he dropped them there. As for the academy, Thomas Kuhn wrote "The Structure of Scientific Revolutions", where he argues that most paradigm shifts happen in revolutionary leaps instead of incremental improvements. We've been pushing back the timelines of human expansion for a long time. It was impossible and just fables that Vikings were on North America, until it wasn't for example.
