  I think that most athiests would really be agnostics if they thought about it. Athiesm is illogical. You can't know that something doesn't exists - unless, of course, you know everything. The most that you can say is that, to your knowledge, you have encountered no evidence of God's existence. It's like saying that there are no aliens. Unless you're omnicient, you can't prove that there aren't aliens.  This is the argument all religious people use in vain. It is not up to the atheists to disprove any biased claims put forward by religious people. It's the people that make the claim that has to prove it.
