Trouble is that when it comes to religious theories, very smart people can believe some really dumb things.
But that is JMO.
That’s true. Otoh, there are a lot of religious people who don’t believe the pyramids were built for grain storage.
But it isn't as though he could have pleaded "My religion DEMANDS that I accept the doctrine that the pyramids were all built during the lifetime of Joseph - and not over a period of thousands of years - and by order of Joseph, in order to store grain, even though they offer virtually no storage capacity, each take about 20 years to build, etc."
His religion demands no such thing.
His 2015 response to the question should have been: "I am not an egyptologist, so anything I might say about the pyramids will probably be wrong - even laughable. Also: Such questions distract from the real issues, such as illegal aliens, budget deficits, etc. Next question!"
Or, if he had INSISTED upon responding, he should have said: "I am first going to enumerate the 37 fact-based reasons that the pyramids were actually used as TOMBS - and then refute, on the basis of geometric logic, each and every one of those arguments."
But he was too dumb to consider what effect his actual answer might have.
