I was reading up on creationism this morning, and Wikipedia mentioned that a lot of Americans believe in it:

"Since 1982, between 40% and 50% of adults in the United States say they hold the creationist view that "God created humans in their present form at one time within the last 10,000 years" when Gallup asked for their views on the origin and development of human beings. As of 2012, the percentage of believers decreases as the level of education increases. Only 25% of respondents with postgraduate degrees believed compared with 52% of those with a high school education or less. A 2011 Gallup survey reports that 30% of U.S. adults interpret the Bible literally."

Do you believe in evolution? Or as Gallup put it, do you believe that God created humans in their present form at one time within the last 10,000 years...

ETA: Do you believe the Earth is under 10,000 years old, billions of years old, or somewhere in between?
