The host of the video is very knowledgable, not only in Egyptology but in stone works, the crafting of them, and demonstration with remaining examples of stone works as they remain, in situ, in various stages of progress.
I think he makes a very reasonable case against the geopolymer theory, as the explanation for ALL, ancient grand stone works, and also a good case for our lack of ability to explain how something like the granite box was crafted in the time period it is said to be part of.
He says, rightly I believe, in is own way, that some things in Egpyt were posssibly not created by “classical ancient Egyptians” but inherited by them, used for their own purposes and were made by even much more ancient peoples, of which we know nothing at all.
