The step pyramid is earlier than the material at Giza. The even more ancient stone buildings are clearly even more ancient than the step pyramid. We know when the Sahara dried up (literally just before writing was invented).
There are also large stone structures built in United Kingdom, Norway, and Spain that predate the Egyptian stone structures.
The engineering of stone structures is clearly something that developed in many cultures over many centuries.

Oh just stop it! Comparing stonehenge or the horse outline in a hillside, to Khufu's pyramid doesn't send up any red flags for you? And in Central America there are monuments/pyramids that at certain times of the year produce shadows of serpents on the step pyramid's descending/ascending step railings. Where are the predecessors of those?
