4 in 10 Americans Don’t Believe in Evolution.

In a recent Gallup poll, 40% of respondents declared that they believed in creationism, that God created human beings less than 10,000 years ago. This number is actually down from a high in 1999, where 47% of Americans polled said that they believe in creationism.

Another 38% believe that God guided the process by which humans evolved from their caveman ancestors over millions of years. Only 16% believe in a completely secular evolutionary process, with humans evolving absent any divine intervention. In 1982, that number was as low as 9%.
