Thanks for an interesting article! Carbon data suggests that Göbekli Tepe is 11600 years old, 7000 years older than Stonehenge. Also, the water erosion on the Sphinx and a lot of other evidence suggests that the culture that built the pyramids is way older than what you suggest in your article.

I would recommend that you look into the work of Graham Hancock and his colleagues. His Joe Rogan podcasts are interesting!

Semir Osmanagić suggest that the Bosnian pyramids are about 25000 years old.

Still, an interesting read!
