This poll is quite different from other polls I’ve seen, the agnostics have never been this high:

Nearly half of Americans are not sure God exists, according to a poll that also found divisions among the public on whether God is male or female or whether God has a human form and has control over events.
The survey conducted by Harris Poll found that 42 percent of US adults are not “absolutely certain” there is a God compared to 34 percent who felt that way when asked the same question three years ago.
Among the various religious groups, 76 percent of Protestants, 64 percent of Catholics and 30 percent of Jews said they are “absolutely certain” there is a God while 93 percent of Christians who describe themselves as “Born Again” feel certain God exists.

When questioned on whether God is male or female, 36 percent of respondents said they think God is male, 37 percent said neither male nor female and 10 percent said “both male and female.”

The born again number is a concern, shouldn’t that be 100%? 🙂
