If you reckon that the existence of God has less than a 1 in a trillion chance of being true, based on all the available evidence, but not proof, can you call yourself an atheist? And if so, would you still be irrational?
I think one can be much less certain that God does not exist and still be an atheist. Atheism is a belief, like a belief that elves and werewolves don't exist. If you're only about 50% sure, then "agnostic" is probably the best label for you, but once you start getting in the 80-90% confidence range, "atheism" is simply the best description.
Obviously, these probabilities are only estimates as there is no easy way to quantify the evidence.
Anyway, I thought it would be fun if everybody (theists included) chipped in on what they thought the odds of God's existence are. To clear things up, we'll specify that "God" refers to a being which continues to interact with the world, as opposed to a Creator who's been hands-off ever since. In fact, why not list the odds of various beliefs? Please list the following:
(1) The odds of a personal God (i.e. one who interacts with the world) existing.
(2) some major form of Catholicism being true.
(3) some major form of Protestantism being true.
(4) some major form of Judaism being true.
(5) some other major or minor religion being true.
(6) something like deism or pantheism being true.
Please list your denomination, if any.
