Not even close. There is zero, nada, no evidence of a culture that old capable of building the sphinx. I suppose you also believe in flying pyramids.
You want to make it personal, but I'm a much better person than you.
The Sphinx as we see it today, with the dressing blocks and the recarved head, is a mixture of very ancient erosional features. The massive stones of the Sphinx and Valley temples were quarried right out of the Sphinx enclosure, and then the walls of both the enclosure and the temples were exposed to rain for thousands of years.
During or after the Old Kingdom the temples were excavated and their eroded faces refaced with stone brought from elsewhere.
The rear of the Sphinx was carved out well after the area in front, which means there were at least two phases of building.
IOW, the Sphinx is itself the evidence of predynastic culture capable of building in stone.
Take your abusive troll BS somewhere else.
