In spite of being raised in a Christian family, I am a firm atheist.
I have, at several times in my life, tried to believe in a god, or a supernatural power, or a spirituality, but any time I did, it always felt instinctively dishonest. And not matter how hard I wanted to believe, I have never witnessed anything in my life which could not be explained my a basic understanding of science.
I do miss church, though. Don't get me wrong, I'll never go back to another church, because I believe that what happens there is abusive and dishonest. I see it as a form of government-sanctioned brainwashing. But, I do miss it. Churches are communities, where many friendships can be born. And there's something nice about seeing people dressed nicely -- these days, everyone (even well-to-do people) seems to make an art form of looking like a slob who just rolled out of bed.
