Geopolymerization and Megalithic Structures
|Examples of the precision of construction in Megalithic Structures|
There is a theory that the Pyramids (and other Ancient megalithic structures) were made from "Geopolymerization" which is essentially "making rocks." It's similar to poring cement - but after it hardened it would be rock that is almost indistinguishable from natural rock.
