Where did I get such an idea? The Huffington Post:
During a stop in New Hampshire on Thursday, Republican presidential candidate Rick Perry raised skepticism about the theory of evolution.
"How old do I think the earth is? You know what, I don't have any idea," said the Texas governor when asked about his position on the issue by a woman and her son. "I know it's pretty old so it goes back a long long way. I'm not sure anybody actually knows completely and absolutely how long, how old the earth is."
Perry regarded evolution as "a theory that's out there" and one that's "got some gas in it." He added that in the Lone Star State both creationism and evolution are taught to students in public schools. He explained, "I figure you're smart enough to figure out which one is right."
