<HTML>Hi, Dave, and welcome to the Ma'at boards!
You noted that: "They do look natural."
Some of us would reply, "That's because they are natural!" (See Chris's and Archae's posts here.)
Both Chris and Anthony noted the presence of machining marks. You can see them yourself if you examine the photos Chris posted, as well as on his website and in his book.
What we find easiest to believe is not always the truth. That's one of the reasons I read these boards so avidly, and I try to remain objective and open-minded. Many things I once believed, I've now dismissed. Yet other theories continue to intrigue, but not convince me. And, personally, I believe that there was an advanced civilization in pre-history that possessed amazing technology, including machining capabilities. Geopolymer? Probably, in some way, shape or form. But pyramid blocks? Alabaster vases? Etc.? I'm not convinced yet.
You wrote,"I really enjoyed learning about Davidovits' reconstituted stone and hard mortars in Egypt." How did you learn about it? Did you actually learn about it IN Egypt? I'm curious!
Ooops. Am I getting off topic?
