Strongest evidence for this to me is Gobekli Tepe and the Sphinx. Massive constructions, yet built before the supposed invention of mass agriculture and domestication of many crops.

Also the frequency of 'Great Flood' events in recorded ancient cultures. My theory is that the middle east region was green during the last ice age, during which there would have been huge volumes of water locked as ice for tens of thousands of years at the poles. As the planet warmed there could have been a catastrophic break in the ice that released a shit load of glacial melt at once.
