Not sure if it touches upon it specifically, but you might want to look into some of Graham Hancocks work, he's written extensively on pre-historic civilizations, with speculation concerning the Pyramids, Gobekle Tepe, and rising Mediterranean waters, among others.

Well none of the theories about the impacts are his own, he talks about the

Jim and Bill Vieira are searching for the truth about giants. Might help you.

Sure thing, good luck. it's a very interesting topic

I would suggest Lloyd Scranton for his research on the Dogon and Andrew Collins for his research on Denisovans etc and those who may have been involved with building Gobekli Tepe.

I’ve actually never heard any serious researchers mention the ‘Ancient Builder Race’ and this term seems to come from Goode and Wilcock so I personally wouldn’t give it much weight.

I just realized it’s Laird Scranton, not Lloyd!

I'm totally going to check out that Andrew Collins guy, because that just sounds fun.

The thing is, afaik the only remains of Denisovans that we've found so far... Is a finger bone.

That’s true, but the bone fragments they found provided the DNA to show the denisovans were a distinct population:

“the results of the examination of one of the small fragments, a phalanx (finger bone) of a child aged between 5 and 7, and found within Level 11 of Denisova Cave. The mtDNA signature from the phalanx from Denisova Cave is significantly different from both neanderthals or early modern humans (EMH).”

Yup, totally on board with all that. How you go from finger bone to "this is a picture of what a Denisovan human hybrid looked like" is beyond me though.

Like I said though, totally gonna check out this guys fanfiction. Sounds very imaginative and entertaining

Ah, I know this one. Have fun!

I am not sure who Corey Goode is...

You may enjoy these extended "teasers": 1, 2, 3 and 4 for a pair of movies I bought from the guy who runs this channel, Josh Reeves, he's super down to Earth, can be a little abrasive at times (he is super sick right now). His OLDER shows are the ones that deal with the old builders, his new shows are focusing more on modern expressions of the mystery religion. Here is the fan page with all his old shows not on his channel.

He's kind of like Bill Cooper with ancient history but an Alex Jones accent (he's from the same town Jones grew up in and he HATESSSSS him, lol)

Carl Munck's The Code (or The Matrix). The production quality is terrrrrrible but the content is wow.

The Old Testament and the Nephalim

Jim Vieira did some good research and had a Ted talk before his stupid reality show. Try googling his work before 2014

try commentaries on the Sutra works of Baudhyana, writing approximately 2400-3000 B.C.E. (had detailed proofs for the hypotenuse 2000 years before Pythagoras....) I think the Baudhayana Shrauta Sutra was one of the more relevant ones... the Vedic civilization's astronomical calculations were some of the most advance of all the world pre-"ciivilization"
