Senator Marco Rubio of Florida is among the Republicans being talked about as one who might lead his party to more moderate positions on issues such as immigration. Rubio sits on the Senate science committee, and an interview with GQ  created much Internet buzz  over his statement in response to a question about the age of the earth. "I'm not a scientist, man," said Rubio. "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 seven days, or seven actual eras, I'm not sure we'll ever be able to answer that. It's one of the great mysteries."
