Nobody can entirely shut out the idea of One true God, the creator of the universe and everything contained within. There is no proof against God, none. You can argue this and that have science try to explain everything under the sun and beyond, but you cannot disprove God.
Not all atheists would claim to know 100% that God cannot exist. At the risk of getting into trouble I will admit to being such a person, but in my experience most take Dawkins' view:
“Let us, then, take the idea of a spectrum of probabilities seriously, and place human judgements about the existence of God along it, between two extremes of opposite certainty. The spectrum is continuous, but it can be represented by the following seven milestones along the way.
1. Strong theist. 100 per cent probability of God. In the words of C.G. Jung, ‘I do not believe, I know.’
2. Very high probability but short of 100 per cent. De facto theist. ‘I cannot know for certain, but I strongly believe in God and live my life on the assumption that he is there.’
3. Higher than 50 per cent but not very high. Technically agnostic but leaning towards theism. ‘I am very uncertain, but I am inclined to believe in God.’
4. Exactly 50 per cent. Completely impartial agnostic. ‘God’s existence and non-existence are exactly equiprobable.’
5. Lower than 50 per cent but not very low. Technically agnostic but leaning towards atheism. ‘I don’t know whether God exists but I’m inclined to be sceptical.’
6. Very low probability, but short of zero. De facto atheist. ‘I cannot know for certain but I think God is very improbable, and I live my life on the assumption that he is not there.’
7. Strong atheist. ‘I know there is no God, with the same conviction as Jung “knows” there is one.’
Further on Dawkins writes, “I count myself in category 6, but leaning towards 7....” (The God Delusion, p. 50-51)
Regarding his category 7 Dawkins further says, “I’d be surprised to meet many people in category 7, but I include it for symmetry with category 1, which is well populated.... Atheists do not have faith; and reason alone could not propel one to total conviction that anything definitely does not exist.” (The God Delusion, p. 50-51)
So there you have it. Dawkins thinks there should be very few atheists representing category seven.

Why is it that atheists say they flat out deny the idea of God?
Not all do. Ask the atheists you meet whether they are a 6 or a 7 on Dawkins religious scale.
HEIsRiSen said:
Is it because we haven't proven God with science? Is it because they have lived a rough life or see the hurt and pain in the world and do not see how a loving God would allow it to happen?
The reason each person becomes an atheist is very often different every time. You might think we all lose faith for the same reason, but we don’t. If you want to know you have to ask. Don’t guess. Your guess will most likely be wrong.
HEIsRiSen said:
God isn't just some theory men made up thousands of years ago...
Actually, I think that is exactly what happened.
HEIsRiSen said:
Just like I cannot prove that God exists to somebody, an atheist cannot prove to me or themselves that He does not.
I have proved it to my own satisfaction.
HEIsRiSen said:
There is nobody that can deny that there is a God, they can only announce their disbelief and reasons for not believing. In order to completely deny even the possibility of a God a person would need proof.
Another way to put your argument is to say that a negative cannot be proven, but there is another way to go about this. You may not be able to disprove the existence of a god, such as Quetzalcoatl, but you can ask yourself whether you have any reason to believe in him. Do you have any reason to believe Quetzalcoatl is a real being? Are you, like me, 100% convinced he does not exist? If you do believe in the reality of this god then for the sake of argument choose another in whose existence you do not believe. Once you have found such a god then perhaps you will grasp my rational even if you are not in a position to accept the certainty of my doubt.
HEIsRiSen said:
There is no proof in science...
It is true that science does not disprove God. Science is not in that business. My position on this is probably the same as most atheists. While science does not disprove God, the scientific arguments, for many of us, remove the necessity of God.
HEIsRiSen said:
I'm sure science explains... [things in] even greater detail, but yet they can not explain everything about anything.
This is only the beginning of the 21 century. Don’t assume that those things you consider problematic today will be without answers tomorrow.
HEIsRiSen said:
There is a unknown force behind everything that happens, this force cannot be seen and this force cannot be explained by science.
What evidence is there of this invisible force? HeIsRisen, this may only be wishful thinking on your part.
HEIsRiSen said:
So my answer to the OP is:
Yes, by definition, there is such a thing as atheists, but there is no real reason for anybody to completely shut of the idea of God because they have no proof to prove their disbelief rational. Just as unbelievers have no proof to prove Christians or any other theist irrational.
I am glad you are reasonable enough to accept the existence of atheists. I won’t speak for all atheists, only for myself, but I can tell you I have never seen evidence of God, and in the absence of evidence my belief simply faded away. I wouldn’t have you believe in Quetzalcoatl without reason and I hope you can see that for the atheist, in the absence of evidence, it is reasonable not to believe.
