re: Ancient civilizations. Y or N?

Outside of the sites that are older than we previously believed humans “settled”, there are other instances that show the ancient cultures we know about were built on the back of unknown, older, cultures.

The base of the sphinx has evidence of water erosion. We know that there hasn’t been enough water to cause this in that area of the world for at least 10,000 years. This suggests it was found by the early Egyptians, not created by them. They may have modified the statue later, but they didn’t have anything to do with the creation of the base.

Things like that are what intrigue me. Not the idea that “Atlantis” with flying vehicles and modern technology existed and then just disappeared.
