What percentage of Americans believe in Young Earth Creationism?

I'm not sure. Probably less than a lot of people think though...I am a Creationist but certainly not a "Young earth" creationist; the people who believe that believe in a literal 24 hour a day 7 day creation, when the Hebrew word in Genesis for "day" means eaither "day" of "time period," so I don't believe in a literal 7 day creation; I believe in a 7 "time periods" creation, so the earth could be a billion years old or thousands. Who knows?
