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 now 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 am not an atheist. An atheist is someone who has compelling evidence that there is no Judeo-Christian-Islamic God. I am not that wise, but neither do I consider there to be anything approaching adequate evidence for such a god. Why are you in such a hurry to make up your mind? Why not simply wait until there is compelling evidence?

Carl Sagan

The most compelling evidence for God's existence is Christ. If God does not exist, then Christ was the biggest fool who ever lived.

Peter Kreeft

When someone like myself points out the rather obvious and compelling evidence that God is cruel and unjust, because he visits suffering on innocent people of a scope and scale that would embarrass the most ambitious psychopath, we're told that? God is mysterious.

Sam Harris

I am an atheist because there is no evidence for the existence of God. That should be all that needs to be said about it: no evidence, no belief.

Dan Barker

The evidence for evolution is so compelling that the only way to save the creation theory is to assume that God deliberately planted enormous quantities of evidence to make it look as if evolution had happened.

Richard Dawkins

Even if the absence of evidence for a given god were not evidence of its absence, it would still be evidence that the belief in that god is unreasonable. That's the only proposition that any atheist of any kind has to demonstrate in order to win the argument. Because anything beyond that... is just having fun.

Scott Clifton

To a certain extent I am taking a leap of faith. I'm adding up the evidence on either side, and I'm seeing the evidence of there not being a God is overwhelming compared to the evidence for there being a God.

Julia Sweeney

There's another way to phrase that and that is that the absence of evidence is not the evidence of absence. It is basically saying the same thing in a different way. Simply because you do not have evidence that something does exist does not mean that you have evidence that it doesn't exist.

Donald Rumsfeld

Most scientists who are religious look for God in what science does understand and has explained. So the way in which my view is different from the creationists or intelligent design proponents is that I find knowledge a compelling reason to believe in God. They find ignorance a compelling reason to believe in God.

Kenneth R. Miller

Emotionally I am an atheist. I don't have the evidence to prove that God doesn't exist, but I so strongly suspect he doesn't that I don't want to waste my time.

Isaac Asimov

Until recent times, absence of evidence for his [Jehovah's] existence has not been sufficient to rule him out. However, we now have enough knowledge that we can identify many places where there should be evidence, but there is not. The absence of that evidence allows us to rule out the existence of this God beyond a reasonable doubt.

Victor J. Stenger

Atheist’s denial of God’s existence needs just as much substantiation as does the theist’s claim; the atheist must give plausible reasons for rejecting God’s existence.

Paul Copan

As a matter of fact, no one knows that God exists and no one knows that God does not exist. To my mind there is no evidence that God exists - that this world is governed by a being of infinite goodness, wisdom and power, but I do not pretend to know.

Robert Green Ingersoll

I have concluded the evident existence of God, and that my existence depends entirely on God in all the moments of my life, that I do not think that the human spirit may know anything with greater evidence and certitude.
