Educated cavemen.

Egyptologists have not believe the great pyramids were built by slaves in a very long time. They consider them "conscripted labor" even now and name it "corvee labor"; a sort of tax on labor. Egyptologists speak "highly" of the pyramid builders except that they ascribe only religious and superstitious beliefs as their motivation. If you want someone to speak at your funeral, don't hire an Egyptologist.

This is similar in all the descriptions of ancient practices into the stone age; people are invariably ascribed primitive and superstitious motivations. Cavemen simply didn't survive by employment of shamans or charms but by observation. It was the natural science built on observation that allowed man to progress to building pyramids and going to the moon not superstition. Superstition mostly arose with the advent of modern language.
