Atheists generally believe there is no god because there is no evidence to suggest that there is one. It's easy to suggest examples of hypothetical evidence which, should it appear, would change their mind (cf my post above, but also Haldane's 'Fossil rabbits in the Precambrian').
Religious people believe despite the lack of evidence, and there is no evidence that you can suggest that would make them change their view (indeed, the whole 'virtue' of faith is that it is maintained despite the lack of evidence)
