Plato learned from the Egyptians that there was once a civilization called Atlantis that existed nine thousand years before his time. Plato wrote about the lost continent of Atlantis in two of his dialogues, Timaeus and Critias, around 360 BC.
Historians and researchers have long debated whether this pre-flood civilization was purely mythological or actually existed. Arguments have been made suggesting remnants of Plato's destroyed civilization could be found at the South Pole.
