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?

The horse outline is relatively modern. Stonehenge is far older than ANYTHING in Egypt.

Regarding the fancy dan pyramids in the Americas, they have their predecssor developments only recently recognized. There are entire mud cities that folks thought were just piles of dirt.

BTW, the Chinese had ships with ocean going capability by about 1875 BC ~ and probably used them.

The Great Pyramid and Stonehenge were built by the same people. The Sphinx is much older but wasn’t so much built as hammered out of an outcrop. Anyway, none of this stuff is all that old. 30,000 BC is old.

The pyramids at Caral, Peru are as old as or older than the pyramids in Egypt.
