And if you are wrong , eternity is a long time.

[Ryantology]

but what are you risking?

An eternity is a long time.

There are so many gods, even if we assume that any of the human religions are right instead of none of them, that our chance of actually picking the right god to believe in is pretty much infinitely small, so why bother?

If anything, going atheist is your best bet, because you have less of a chance of pissing off the right god for believing in a specifically wrong god.
