And of course that is not to mention that, depending upon your reading of the various sacred texts, taking Pascal’s wager and believing in god also likely entails the risk of believing in the wrong god…which is pretty much a crapshoot, since any belief in one god goes against the convictions of a few billion other people.
But to properly answer your question, along the lines of Maverick, what god has done for me has been basically bad: he has left on earth billions of people who still believe, and who therefore take it upon themselves to screw up human life on earth as much as possible. Politically, socially, even morally. Wars, religious justifications for racist and homophobic violence, corruption and moral hypocrisy. There is no such thing as an ethically innocent believer in my book.
Of course, not believing on some level is also very difficult. But I try.
