What do you think of an Atheist/ about Atheism ?

I think Atheism is illogical.

I don't see what is illogical about it at all. I consider myself myself an atheist because while I do have some personal beliefs, I do not believe in the existence of a God, and I have very strong views against any form of organised religion. I can accept that it is something that cannot be proven one way or another, and personally I wouldn't make a flat out statement like: God doesn't exist - because I recognise that without proof it is just an opinion. But for me God doesn't exist, I don't think there's any evidence in the world that could convince me otherwise, and I don't think that is an illogical statement to make in that context.

If you believe that God exists, then for you he exists. If somebody else believes that he doesn't exist, then for them he doesn't.
