Some religions have their own versions, but the actual AA meeting is not tied to a religion, but the higher power, like others stated.
You can still be an atheist and believe in the higher power they speak about... assign it to anything you feel is important, the universe, compassion for humanity, family love....
I am a questioning Christian/Agnostic/Universalist, lol! I don't think anyone is screwed, I think we all just need to try our best and help each other :)
