Why the Pyramids Spawn So Many Wacky Theories

GOP presidential candidate Ben Carson stands by an odd theory he floated at a commencement address: that the Egyptian pyramids are not pharaohs' tombs, but ancient grain silos built by the biblical Joseph. Indeed, though the pyramids are some of the most well-researched ancient structures in the world, they have a long-standing tendency to attract crackpot theories. Like Carson, these people ignore massive amounts of contemporary evidence about the pyramids.
