An Important Hint Linking Atlantis & Younger Dryas

As we know, Plato places the destruction of Atlantis at 9.600 BC. This specific date happens to also be the abrupt end of Younger Dryas. Although this is direct, there is another hint given by Plato which places the end of Atlantis to the end of Younger Dryas.

Plato tells us that sometime after the defeat of the Atlanteans at the hands of the Athenians, Atlantis sunk to the sea within a terrible day and night of earthquakes and floods. The Atlanteans were not however the only victims of this catastrophe, as the entire Athenian army was lost under the waves.

So the same catastrophe affected in the same way two rather distant areas of the earth, Atlantis being on the Atlantic Ocean just outside the straits of Gibraltar, and Athens being in the east Mediterranean. This implies that this catastrophic event affected a large part of the globe. And what event could have had such widespread effects? Precisely, the end of Younger Dryas.

So if someone wants to argue that the date of 9.600 BC was a lucky guess by Plato, there was another equally lucky guess that the "imaginary" catastrophe was of a planetary scale. Really, what are the chances of Plato two such lucky guesses in a row?
