This held my attention pretty well. I thought it was a bit overly rhetorical at parts and that the editing of (most of) his interviews with field experts or "buffs" (his term) really zeroed in on whatever sound bits propagated his precise message, otherwise ignoring most of what they might've contributed.
Some of the reviews here state that he offered no "proof" of a prehistoric advanced civilization, and that pyramids, stone temples and such are not "advanced". On the contrary, the point he's trying to argue is that a global cataclysm would've wiped out all traces of any prehistoric advanced people, and that if there are traces, they may exist in places we haven't looked or been willing to look (which he gives examples of). He's arguing that, in fact, the scale of construction endeavors (megaliths, pyramids, subterranean structures), and the astronomical designs/orientations seen in them are advanced enough to suggest a level of knowledge and sophistication that could only have been passed down from earlier humans, thus indicating that they must've been constructed at more of a resource, technology, and population 'reset' than the beginning of human life as we know it. In other words, the primitive hunter-gatherer groups that archaeologists currently believe were the earliest humans couldn't have just up & created these structures, all at around the same time--nor would they have had any reason to unless motivated by stories of fear & suffering from an apocalypse.
He dumps on archaeologists a lot, but seems to offer some reasonable explanations for it: he says they discount theories while refusing to look into them; that they refuse to excavate certain places; that they are not motivated to correct people's understanding of history even as new science proves old science to be incorrect.
I can see that, to be honest. It's not that I know much about archaeology specifically, but it is a field wrapped in academia, which comes with all sorts of funding, political, and bureaucratic issues, all while the people involved are necessarily as passionate about furthering their own careers (and maybe supporting themselves) as they might be about furthering human knowledge. Ideas/projects that get funding are often within the comfort zones of various interconnected institutions, following ever similar paths, expanding on existing ideas, etc. This kind of thing exists all over academia. Look up Drs. Karikó and Weismann re: how long it took to get funding for mRNA vaccine research, for example.
I'm gonna find myself some popcorn and look forward to hearing/reading any archaeology community response to this.
