Has this been said? The reason I'm an atheist is straightforward. The proposition that there is a god is as unlikely as ghosts, Martians amongst us, and reincarnation. There isn't the slightest evidence for these hypotheses which fly in the face of so much else that we know to be true. So I believe all of them to be false.
I admire religious belief in God. Most religions I find beautiful and noble.
And yet there are few atheists. And most atheists don't fancy religion.
