Now everyone will be surprised. The Sphinx was originally Anubis/Anpu with a larger head.
The body is disproportionate to the head because it was added there during later dynasties. The modern Sphinx is not the "original".

The Egyptians may have "remade" monuments by re-carving or altering previous works and claiming them as their own. Ramses II became famous as the "Great Usurper" for all the works he appropriated for himself.
