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. Intriguingly, this also corresponds to the period when the geological age of the Younger Dryas suddenly ended with an abrupt warming of more than 10°C in only a few years. This event marked the beginning of the Holocene, the era in which we are still living today. Sea levels must have risen rapidly and dramatically, and as a result entire civilizations, if any existed, would have disappeared under water. Read more: https://www.spaceandintelligence.com/...
