*Shrug*

Go on, be like the Evangelicals, as unreasonable as an iron pot.

The comment is very widespread, and widely believed, even by many atheists.

It's not to say that Atheists suddenly find religion, but that your belief in absolutely no higher power what so ever is unlikely to hold up under repeated bombardment. There are very few people, when being bombed, or shot at, or hanging off a cliff, who won't say "Oh God, please let me live through this."

Saying you'd never be that person is exactly like a Christian saying he'll never have a crisis of faith.
