Been reading Graham Hancock's books since Fingerprints of the Gods in 1995 (one of the few authors and researchers of this type of material that seems to hold any weight, as opposed to the numerous kooks out there, including those from the 70's on), and found this discussion interesting. In case anyone else might be interested in the possibility of a pre Younger-Dryas civilization.
It's about an hour long, so put it on 1.5X (or whatever is preferred) speed.
Keep in mind this is an alternative perspective to the mainstream academics, who dismiss him with prejudice, but also keep in mind that some of his ideas from a couple decades back have been somewhat substantiated by more current findings.
Take it with a grain of salt, but consider it for it's interesting possibilities, aspects of which hold up to scrutiny.

now, when you see a progression from rudimentary to advanced, a more-or-less complete transition from gatherer to cultivator, that makes the proposition that something had been previously advanced and wholly lost, only to be discovered from scratch, rather unlikely. remember, agriculture is revolutionary, and revolutionarily productive. its not something any population would forget, and it is technology which quite rapidly proliferated once discovered DURING the younger dryas.
GH's notions of radical sea-level change are also derided, and his propositions are now converging into a more reasonable notion that there are relict villages/towns on various low-lying areas now submerged by ice-age melting. but that isn't any great trick of imagination.
"Hancock has modified his concept of a global civilisation that sank without trace and now propounds the idea of a number of maritime cultures, many of them interlinked, which succumbed to inundation as the ice caps melted. He has introduced a degree of gradualism into his hypothesis " https://www.theguardian.com/education/2002/feb/06/artsandhumanities.highereducation
Indeed they do, and your thoughts there should be considered. However, they're baffled by, and handwave away real explanations of, Gobekli Tepe, which is dated to about 9600-8000 BC, a discovery that smashes the previously accepted timelines. Like any aspect of science, nothing should ever be considered settled, and is constantly evolving as new information comes to light, i.e. no theory should be either believed, nor dismissed, including Hancock's. Even though he's been off the mark a few times through his run, so have mainstream academics, who don't have any better of a track record (but who try to cancel any ideas that don't fit in with their own, often ideas they end up accepting a few decades later when the evidence is too overwhelming to continue to deny--it takes a while because there' s a lot of egos and politics and money that get in the way). But I do find Hancock's ideas and research interesting food for thought, and tend to always question mainstream "accepted" concepts since they are often later found wanting.

certainly paleoanthropology has been turned upside down in the past 20 years - but that is largely based upon the narrow platform in the fossil record - so any distinctive find prompts wide-ranging re-evaluations. we've gone from rejecting global multi-regionalism, to thorough-going intra-african multi-regionalism, leading to a very bushy theory of human evolution.
this happened because people are looking for evidence, advanced sometimes by those who chose to look in new or long-neglected places, like Berger in SA, in discovering the weird & wild naledi population.
if hancock uncovers anything independently which advanced the field, he should get credit, in that unlikely event. but his credibility is not good. and he is certainly not the only person taking a look at gobekli tepe, nor was he discoverer.
part of his schtick is selling the notion that science is a hidebound enterprise that only a few intrepid souls such as himself are taking a 'fresh' look at :). alt-science relies about such embellishments, though in various times & places, that caricature hold (during the age of religious orthodoxy, piltdown man, 'soviet' & 'aryan' science).
we're past that, other than the domination of research dollars by corporate interests.
