Robert Schoch agrees that original head on The Great Sphinx was the Lioness deity Mehit.
Schoch should stick to geology - a subject he gets wrong even then.
The Sphinx was likely a Egyptian dog - the symbol of Anubis, the guardian of the dead at the necropolis of Giza. Facing East as Ra was reborn each morning; served as the Horus on the Horizon line; part of the huge geometrical Giza design.
During the First Integrum most of Giza was vandalized and what could be smashed was destroyed, Later In the Middle Kingdom, the stump of the head was re carved in the likeness of the then current pharaoh, Amenemher II (1876-1842 BC), which we see today.
Again Schoch is a nutter trying to make a case for something he knows professionally nothing about, nor does he know anything about what the Sphinx was originally used for - which would more than account for his age of the Sphinx theory.
Since I was a little kid I always thought the head on the sphinx was somehow ‘wrong’.
Given the artistry of the structures all around it, it would be stunning for them to create it with a head so out of proportion.
It clearly was also buried, for a long long time.
So, my theory is that it was built far longer ago than we know, there was a flood, it was buried, and only the head was sticking out. After a few thousand years the head erodes away and just looks like a big rock.
So they carve it into a Pharaoh’s head, maybe not even knowing a whole feline body is underground.
