Who built the Great Sphinx?

Michael Beattie Most Egyptologists think that the Great Sphinx was built by King Khafre, the builder of the second of the pyramids at Giza, who ruled from around 2558 to 2532 BCE. Some believe the Great Sphinx started out as a statue of a lion, with Khafre’s features added later. This combination of man and beast represents the pharaoh’s super-human power: the sphinx suggested that the king was a god on Earth. It may also have been intended to serve as a guardian of the king’s pyramid.
