Actually, I do not happen to think that pyramids as graineries are that much of a stretch. It has been shown that pyramids have an effect on freshness of milk. Don’t you remember the Tetrapac, still in use widely in Europe?
I have read a great deal about pyramids in Egypt, and never once heard a suggestion that they were used for graineries. The space inside is much too inefficiently small for grain storage, they were filled with burial goods for the occupant (before looted by grave robbers), information about the occupant was clearly inscribed on the interior walls, and they were mostly much to far away to be of any use as storage for an urban location.
Pyramids don’t sharpen razor blades, or keep food fresh. And no, the pyramids were not used as granaries. Of course, none of that means much regarding Carson’s fitness for office — his biggest problem has been in hiring the wrong people to run his campaign.
