This is Marco Rubio speaking directly to the lunatic base of the Republican party. He clearly wants to get out ahead of the game of winning the hearts and minds of future primary voters.

GQ: How old do you think the Earth is?
RUBIO: I’m not a scientist, man. I can tell you what recorded history says, I can tell you what the Bible says, but I think that’s a dispute amongst theologians and I think it has nothing to do with the gross domestic product or economic growth of the United States. I think the age of the universe has zero to do with how our economy is going to grow. I’m not a scientist. I don’t think I’m qualified to answer a question like that. At the end of the day, I think there are multiple theories out there on how the universe was created and I think this is a country where people should have the opportunity to teach them all. I think parents should be able to teach their kids what their faith says, what science says. Whether the Earth was created in 7 days, or 7 actual eras, I’m not sure we’ll ever be able to answer that. It’s one of the great mysteries.
Actually, it isn't a mystery at all. The earth was not created in seven days. The earth is not only 6,000 years old. Man did not walk alongside dinosaurs.
I don't think Rubio is as dumb as he's pretending to be, so I'll chalk this up to him establishing his conservative street cred.
