I'm not all that bothered by the crazy "pyramids-built-to-store-grain" theory.  If government officials were disqualified for believing something residing in ancient history that is unprovable and that most of the world views to be outlandish, there wouldn't be many Christians in the government. 

I hope that Dr. Carson can draw upon his problem-solving skills developed as a surgeon to think out of the box to solve long standing urban housing problems.
