But I do. My morality doesn't come from an imaginary being. It comes from my relationships with other people. I don't kill people because (a) it would bring me no joy to do so, (b) would bring me no benefit, and (c) we have laws that prevent killing because societies are more stable when they don't engage in random killings. Societies only get to exist if the people in them find a net benefit in staying alive and having others stay alive. It's amazing how many cultures have existed throughout our history as a species and none of them just went crazy because they didn't believe in some land-locked storm god who forgot about his wife.
The idea that people are just going to go apeshit if they truly believed there wasn't a god is right up there in terms of ridiculousness with all the men in the Republican party and pastors who claim steadfast morality but keep getting caught with minors, women who aren't their wives, and gay men. So I feel sorry for you if you are so inherently immoral that you need to be held back by stories of a man in the sky, but some of us don't live our lives in fear of supernatural retaliation.
And if we're being real, the vast majority of the planet don't believe in your god, including people who claim to be Christian. It's just easier to say that you do so that people will leave you alone.
