You need to check out the new movie on You Tube about the pyramids which incorporates a lot of theories about pyramids including construction method, mathematics of pyramids, purpose, widespread construction worldwide and not also theorizes that the original people of these achievements were black “Africans??” from Egypt who traveled worldwide with their pyramid technology (including those we know as Olmecs)
I think the title is something like Pyramids, the Movie and it runs over 3 hours to present and consolidate all the theories. I found myself fascinated by the way all the physical evidence was presented by using actual photos, videos, and graphic displays to explore a plausible (if far out)mega theory.
Okay, thanks.
