OK, I'll try and explain MY personal view of it. But realize, there are atheists that agree with you as well, although I think the vast majority don't. This is only my view. I claim no affiliation with a movement or group of other atheists.
Here we go.
I do not have a belief that there is no god. This is not a belief of mine. I believe there is zero evidence suggesting there is a god. And lacking evidence, it seems very unlikely. So I do not have an active belief in god. I don't trust that there is no god, there could be. I simply don't have a belief in god. It's possible, but so unlikely to me that it's not worth contemplating beyond how the belief system effects society, which I find very interesting.
So I think about it, but not about the "believe or not believe" portion. There is not much to contemplate regarding the existence of god, at least for me. If you want my fuller thoughts on it, I think it doesn't matter what we believe because I can't imagine a god that would actually care if I believe or not. The concept that something all powerful would care if we have faith seems ridiculous to me. So either there is no god as I think is most likely, or there is a god that is totally separate from the individual at this point.
I am fully aware that you will look at what I said and say I am agnostic, not atheist. This may simply be a matter of differing definitions, but I find the likelihood of god so remote that for all practical purposes I have no belief in god. I do not hold open doors just in case God is real. I do not know that there is not a lockness monster, but the evidence is such crap that I have no belief in it. I don't know it doesn't exist, but I simply find it highly highly unlikely. However, I find Nessy more likely than God, or at least any religious version of God.
