From GQ magazine's interview with Marco Rubio:
GQ: How old do you think the Earth is?
Marco 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.
This isn't some crank Republican like Dana Rohrbacher. This is the guy people are talking about for President in 2016. It's not just wrong, it's illiterate. It's a pre-1900 understanding of the world and universe.
Teaching "all" the theories, as Rubio wants to, does impact the economy, in that it results in a scientifically illiterate generation of people. The future geneticists of America need to know that evolution is the only theory of origin of species. They need to know that the animals were not loaded 2 by 2 onto a boat before a huge flood. They need to know that a great flood can happen, despite the promises of a fictional god in a fictional old book to never do it again and will happen without intervention into the current state of climate.
