Morning Joe hosts scorch Ben Carson: Does he think Noah built the Eiffel Tower, too?

The Morning Joe crew found themselves wondering about Ben Carson’s worldviews after learning the 2016 candidate still believes that the biblical figure Joseph built the pyramids in Egypt to store grain.

Carson's theory first came to light when Buzzfeed found a video of his commencement speech at Andrews University, in which he said, "“My own personal theory is that Joseph built the pyramids to store grain." The university is associated with Seventh Day Adventists, an evangelical Christian faith the retired neurosurgeon adheres to. During the speech Carson also said some scientists believe aliens built the pyramids, which is not true.

"It doesn't require an alien being when God is with you," he had said.

When asked about the comment recently, Carson doubled down.

"The pyramids were made in a way that they had hermetically-sealed compartments. You wouldn't need hermetically-sealed compartments for a sepulcher. You would need that if you were trying to preserve grain over a long period of time," he said.

The Morning Joe hosts seemed to be left speechless by the comments.

"I'm completely speechless, I mean what can you say about that?" journalist Eugene Robinson said.

"Yeah but you could say, 'I was drunk when I gave that speech and now I take it back,'" Joe Scarborough suggested.

Robinson then said Carson's theory begs a lot of "follow-up questions about history."

"In this case, I kind of want to know now how old Ben Carson thinks the earth is," Scarborough said. "If you say something like that you -- for a conservative, opened the door. Do you believe the earth is 5,000 years old. Do you believe its billions of years old? Because this is some really, really quirky stuff... I wanna know if he thinks Noah built the Eiffel Tower."
