An overwhelming majority of Americans believe in God and signicant numbers also think that UFOs, the devil and ghosts exist, a poll showed Tuesday. The survey by Harris Online showed that 82 percent of adult Americans believe in God and a slightly smaller percentage -- 79 percent -- believe in miracles.
More than 70 percent of the 2,455 adults surveyed between November 7 and 13 said they believe in heaven and angels, while more than six in 10 said they believed in hell and the devil.
Almost equal numbers said they believe in Darwin's theory of evolution (42 percent) -- the belief that populations evolve over time through natural selection -- and creationism (39 percent) -- the theory that God created mankind.
Seventy percent of Americans said they were very (21 percent) or somewhat (49 percent) religious, while around one-third of those polled also said they believe in UFOs, witches and astrology.
