I liked it, though the Sphinx was build thousands of years before Egypt, and there is now evidence that ancient civilizations existed 12 000 years ago and were much more advanced than we think. It is very likely that it was Atlantis and they were corrupted by greed and power just like we are now and began falling apart. They were buried by something giant that came from space and hit Earth creating a massive flood, traces of which can be seen all over the US (like the Grand Canyon), though evidence suggest that not all of them died and the survivors spread all across the world sharing their knowledge of civilization and building these ancient sites, that's why the buildings are very similar in architecture.
