In 360 BC, the famous Greek philosopher Plato wrote about a battle between his city Athens and a great empire named Atlantis. In two of his books, 'Timaeus' and 'Critias', Plato describes this war that ended when Atlantis disappeared in the ocean, due to "violent earthquakes and floods". According to Plato, all this happened 9.000 years before his time which would be at least 9.400 BC, some 12.400 years ago.
