Fair enough but what he is doing is allowing Hancock and Carlson to express themselves. The idea that there may have been older civilizations that were destroyed because of a great cataclysm is interesting. They are trying to show with the evidence available that it may be the case. In total he has them on his pod cast for about 20 hours over maybe 8 episodes.
Hancock had a theory that those civilizations where destroyed by pole shifts, floods or something. When he along with Carlson suggested it may have been a comet people said where is the evidence. 2018 comes along and NASA discovers this:
The crater is what was needed to show they might be on to something. New information always has it's detractors because it can literally wipe out a career's worth of study in a second. No one wants that and it usually only happens once people have died. What benefit do Egyptians have in accepting that there was a advanced civilization before them, none. There claim to fame is they were the first. Gobekli Tepei comes along which predates them by 4000+ years and it gets people thinking. What Egyptologist would want another culture to take that away?
What if Egyptians moved into the pyramids because they were already there and claimed them as there own? What if cavemen were people who were forced to take shelter in caves because it was the only way to survive a great impact? What if the Pyramids were built to withstand anything because people knew comets could destroy them?
We are trained to believe we evolved from apes or from Adam & Eve but both could also be bullshit. You don't go from living in caves to hunting and gathering to pyramids in a span a a few thousand years.
Understand what they are saying before you disregard their theory. If they are full of shit so be it. It doesn't make it any less interesting.
The two Greenland craters have an age range based on dating between 50,000 and 79,000 years according to NASA. The Young Dryas Impact hypothesis I'm sure you're referring to is just that, a hypothesis. There is no substantiated evidence that it was a real event, research that has been done on it has often failed peer review and been debunked, and it remains unproven. Those Greenland impact craters are certainly not evidence of it, regardless of what youtube video you watched claiming that they were.
You use the term "cavemen" as if it was ever common for humans to live in caves, it was not. Only a very small number of humans have ever lived in caves as suitable caves are not common throughout the world, and they are far from hospitable environments for humans to live in.
"Egyptians moved into pyramids"? My f***ing god. Egyptians did not live in pyramids, and pyramids were only constructed as tombs for pharaohs, and most of them are not even buried in pyramids because they were widely robbed even in the ancient world, so they mostly used underground tombs in the Valley of the Kings. Pyramids are built the way they are because based on the engineering and materials of the time it's the strongest design that there is, and pharaohs intended for their tombs to last forever.
"Apes or Adam & Eve"... Yikes. You are presenting two things like they are equivalent ideas when they are not, please go do some research on the theory of evolution and natural selection. For one, natural selection is a fact. There is no disputing this, the science is settled and our entire understanding of biology and all of the developments from it are based on it. The theory of evolution is one of the most substantiated scientific theories that there is, there is overwhelming evidence to support it. Homo Sapiens did not "evolve from apes", Home Sapiens are apes (hominids specifically). We share a common ancestor with other extant primate species.
Where did you get "a few thousand years" from? Seriously, did you just make that number up? Anatomically modern humans date back at least 190,000 years, and possibly as far back as 500,000 years. What we classify as the beginning of civilization development (i.e. complex societies that are agrarian and urban) dates back to about 12,000 years ago to the Neolithic Revolution, with the earliest known civilization (Sumer) dating back about 6,500 years ago. Even saying that, there were many developing civilizations before that in the Neolithic period in Mesopotamia, Egypt, Syria and the Levant, Anatolia, Iran, the Indus River basin, the Yellow River basin, etc. The growth of civilizations is a slow development process over time, it's not like one day a switch was flipped and suddenly Ancient Egypt existed. So when you talk about Ancient Egypt being the first "advanced civilization", I really have no idea what the f*** you are talking about.
Gobekli Tepe is an interesting site and not at all support for what pseudoarcheologists claim. It's a site that was not built all at one time and like most ancient sites was developed over thousands of years to the outline that we have discovered today, with much of it still uncovered. Our current understanding of the site was that it was constructed by a predominantly hunter-gatherer society that lived in the area in villages close to their hunting ground for at least a portion of the year. Based on the evidence found at the site of bones from a wide range of game, the layout and structures there, and the carvings and drawings, it is thought to have been a central gathering place for the hunter-gatherer societies living in the region, and faded from use after animal husbandry and agriculture developed. It's exact use and such is still not know though. There is also a similar site near the Euphrates in Turkey (Nevalı Çori) that is a few hundred years younger and shares many of the same characteristics. What sites like this say to me, is that our understanding of hunter-gatherer societies is flawed and outdated, and that typical assumptions about hunter-gatherer societies are not the complete picture. It comes off as insulting to these societies as well to dismiss the possibility that they constructed these sites and that some hidden ancient civilization that there is no evidence for must have done it instead, because it's not like the humans who lived there were any less intelligent or capable than we are.
I do understand what they are saying, and they are full of shit.
