>Our ancestors are aliens that's why they were smarter.
Our ancestors were smarter because they still had access to knowledge from previous generations who roamed the Earth for a significant period of time prior to the catastrophes.

This is why there were so many megalithic ruins around the entire planet, not just one remote region in the Mediterranean.
