> That theory is espoused by the same people who think it was built by aliens.
I think this is a common misunderstanding.
Yes, there are some who think aliens built the pyramids.
But there is an equally large group of people who think that humans pre-ice age were advanced like we are today. And when the ice age happened 12,000 years ago - that knowledge was lost.
When you then look at build sites around the world from this perceptive, structures like the Sphinx and others (like Göbekli Tepe), begin to appear much older than convention teachings might imply.

EDIT: for those interested more in this topic, there is a Netflix series on it (called "Ancient Apocalypse"). I can't attest to the validity of the statements made in the series, but the arguments are compelling (and not alien related).
