I love shows like this! I grew up watching Ancient Mysteries and Unsolved Mysteries exploring the finding of Noah's ark on Mt Ararat and talking about Atlantis, but calling this a documentary is a stretch. The definition of a documentary is "a movie or a television or radio program that provides a factual record or report." None of this is factual. It's theories based on speculation, but the reason they aren't considered factual is there is absolutely no hard, scientific evidence for any of it. It's great that he's talking about it, and even I and my husband have thought experiments about an intelligent race of dinosaurs who used organics to build their cities, etc...Hence the reason there is no record in the fossil remains. I would think this is more of a Sci-Fi show, or a fantasy drama than a documentary.
