RE: Ancient Temples: The unknown craftsmanship and design that withstand time.

Some kind of advanced technology in ancient times... That is my theory. This technology must have been lost in time. I'm not talking about laser beams or something fantastic, but something else that these civilizations have developed. Perhaps the library of Alenjandria contained writings on this, but unfortunately it was burned. Or maybe our body was stronger thousands of years ago, and it was easier for us to work the stone, who knows...
