hey i liked this post alot! the fact that there are pyramids in south america as well as egypt and this whole notion of an advanced civilization lost in time is quite fascinating :)
Look into copper. Atlantis was a chalcolithic (copper age) Empire, which is where all the copper in the fertile crescent came from.
Egypt was a near-direct continuation of Atlantis. Same engineering, people and structure. Egyptians were of course white, confirmed 100% by analysis of King Tut
