I'm an atheist: I don't know what it means to believe in God.

I'm caught between the words 'atheistic' and 'agnostic'. I've got no evidence whatever for believing in a God. But I know that all the things I do know are very small compared with the things that I don't know. So maybe there is a God out there. All I know is that if there is, he hasn't shown himself on earth. But going further than that, I would say that those people who claim that they do know that there is a God have found this claim of theirs the most wonderful excuse for behaving extremely badly. So belief in a God does not seem to me to result automatically in behaving very well.

As an atheist, I see nothing “wrong” in believing in a God. I don’t think there is a God, but belief in him does no harm. If it helps you in any way, then that’s fine with me. It’s when belief starts infringing on other people’s rights when it worries me. I would never deny your right to believe in a God. I would just rather you didn’t kill people who believe in a different God, say. Or stone someone to death because your rulebook says their sexuality is immoral. It’s strange that anyone who believes that an all-powerful all-knowing, omniscient power responsible for everything that happens, would also want to judge and punish people for what they are.

I’m an atheist in the sense that I do not believe in God, I do not believe in the afterlife. I believe that the soul is our brain. It’s impossible to scientifically prove either that God exists, or that God does not exist. The idea of God does not convince me. I prefer to believe that there is matter and that matter has the properties we observe. … When I pass away, if I meet God, I will tell him I was wrong.

If there is a God, why did he make me an atheist?

Those who raise questions about the God hypothesis and the soul hypothesis are by no means all atheists. An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence. Because God can be relegated to remote times and places and to ultimate causes, we would have to know a great deal more about the universe than we do to be sure that no such God exists. To be certain of the existence of God and to be certain of the nonexistence of God seem to me to be the confident extremes in a subject so riddled with doubt and uncertainty as to inspire very little confidence indeed.

I believe that there is no God. I'm beyond atheism. Atheism is not believing in God. Not believing in God is easy — you can't prove a negative, so there's no work to do

Even an atheist has to believe that the concept, at least, of "God" does exist, whether or not that concept is true or useful or the best way to approach things.

When we claim that "God does not exist," we mean to deny by this declaration the personal God of theology, the God worshiped in various ways and divers modes by believers the world over, that God who from nothing created the universe, from chaos matter, that God of absurd attributes who is an affront to human reason.

Let us weigh up the gain and the loss involved in calling heads that God exists. Let us assess the two cases: if you win you win everything, if you lose you lose nothing. Do not hesitate then; wager that he does exist.

Why don’t you believe in God? I get that question all the time. I always try to give a sensitive, reasoned answer. This is usually awkward, time consuming and pointless. People who believe in God don’t need proof of his existence, and they certainly don’t want evidence to the contrary. They are happy with their belief. They even say things like “it’s true to me” and “it’s faith.” I still give my logical answer because I feel that not being honest would be patronizing and impolite. It is ironic therefore that “I don’t believe in God because there is absolutely no scientific evidence for his existence and from what I’ve heard the very definition is a logical impossibility in this known universe” comes across as both patronizing and impolite.

I believe in God, although I live very happily with atheists... It is very important not to mistake hemlock for parsley; but not at all so to believe or not in God.

I don't know what God is, or what God had in mind when the universe was set in motion. In fact, I don't know if God even exists, although I confess that I sometimes find myself praying in times of great fear, or despair, or astonishment at a display of unexpected beauty.

An atheist, like a Christian, holds that we can know whether or not there is a God. The Christian holds that we can know there is a God; the atheist, that we can know there is not. The Agnostic suspends judgment, saying that there are not sufficient grounds either for affirmation or for denial. At the same time, an Agnostic may hold that the existence of God, though not impossible, is very improbable; he may even hold it so improbable that it is not worth considering in practice. In that case, he is not far removed from atheism. His attitude may be that which a careful philosopher would have towards the gods of ancient Greece. If I were asked to prove that Zeus and Poseidon and Hera and the rest of the Olympians do not exist, I should be at a loss to find conclusive arguments. An Agnostic may think the Christian God as improbable as the Olympians; in that case, he is, for practical purposes, at one with the atheists.
