Meet The Pyramid Truthers: Where Ben Carson’s Whacky Theory Came From

Ben Carson isn't the only pyramid truther out there.

The GOP frontrunner's theory that archaeologists are wrong and that the Egyptian pyramids were really built by the biblical figure Joseph to store grain wasn't created in a vacuum. In the fringier corners of the Internet, variations of the pyramids-as-grain-storage argument has spawned entire blogs and a 30-minute documentary.

Carson -- who is continuing to defend beliefs that were surfaced this week in video of a 1998 commencement address by the acclaimed neurosurgeon -- joins the ranks of pyramids truthers who believe that, warned by God of an oncoming famine, Joseph built grain storage units that exist today in the form of the ancient pyramids.

His theory flies in the face of what has long been settled by modern archeologists: that the pyramids were built as tombs for Egyptian pharaohs.
