Is it contradictory for atheists to say that they have no belief in God and at the same time say that God doesn't exist.?

How is it contradictory? There is no scientific evidence to prove the existence of deity. You must 'believe' in this being, it is not a fact. Not having this belief they do, then, have a 'disbelief', but they can also say that, according to all known science, this being doesn't exist at all.

Contradictory b/c one is about belief and the other statement is about knowledge?

Not really contradictory b/c if the statement can not be backed up by facts, then you still form beliefs about it. Whether the agree or not. And some might not be aware that the 2nd statement is true anyway. They say you can't prove a negative. Well, the Bible God is said to be all-knowing, all-powerful, and loving and that his god created EVERYTHING. it isn't possible for a loving god to create evil.

Those are different atheists, usually. Some merely have no belief in god, others make the statement that a god doesn't exist.

Neil, Sorry mate you are semantically wrong. Atheism is not the belief that there is/are no god/s it it the lack of belief that there is/are god/s

Atheism and agnosticism are not mutually exclusive. I am an agnostic atheist in that I don't believe any god claims but can not be certain either way.

I am atheist because I do not believe - it is that simple. Neither theism nor atheism say anything about what you claim to know, only what you claim to believe or not.

It is not a belief when you know the truth!!! Actually no gods or devils exist anywhere outside of any ones inculcated minds!!! The inculcation coming from the same con men who preach blah blahs at you in church then after its last amen it goes to the back room of the church and abuses little boys!!! It's been done often enough to be believed just like the religious stories!!!

Not really. They are just different types of statement. That atheists have no belief in God is a statement of fact. That God does not exist is a statement of an atheist's belief. It could be argued that we should not state beliefs without explicitly stating that they are such, but it is something people do very frequently.

Of course not.

Believing God doesn't exist ≠ believing God exists.

What doyou mean by contradictory? If you say you don't believe that something exists then you're saying that it doesn't exist.

''I don't believe that it does'' means ''I believe that it doesn't''

Inigo Montoya: You keep using that word. I do not think it means what you think it means.

If you do not believe that Zeus is real, is that a belief on your part ? Nope. It's a non belief. Just like NOT playing football is a non sport.

really? I have never seen an atom...but without them what would there be? There is no contradiction...only willful ignorance of the nature of semantics and how they figure into dialogue. I talk about Peter pan but don't believe in fairies....
