my archaeology prof has talked about it in class, mostly because it reinforces very colonial ideas that certain populations could not have built these massive structures because they ‘weren’t advanced enough’ in the eyes of white europeans. graham hancock is part of a group of pseudoarchaeologists known as ‘new agers’ who believe that there was a lost civilization that was incredibly advanced, and he (and other new age believers) have a nasty habit of ignoring certain evidence and only investigating things that support their viewpoint. this isn’t a new thing, many archaeologists and anthropologists have experienced these people for many years (there’s a great new yorker article that i’ve linked about the sphinx that talks about them), but it’s dangerous to fully believe what people like that say. it’s not based on all the facts and sometimes pushes very anti-indigenous viewpoints.
