Augustus Le Plongeon first proposed the idea of a lost continent named "Mu", that was originally located in the Pacific but disappeared near the dawn of human history. He stated that many ancient Mayan writings spoke about a civilization which predated Greece and Egypt. He went on to theorize than emigrants from Mu founded the Egyptian and Mayan civilization.
Mu's existence is disputed because "a continent can neither sink nor be destroyed by any conceivable catastrophe, especially not in the short period of time required by this premise."
hmm sound like any landmass we know that CAN disapear in a short period of time?
I really like this idea, that the island's civilization predated Egypt and its emigrants actually founded the Egyptian and Mayan civilizations (explaining why the architecture on the island has similarities to either civilization), and that since ancient times the island has been skipping through space and time, explaining why this lost continent appeared to disappear.
