naomi24, //If there is nothing to believe there can be no belief.//
Have you forgotten about those who believe in god/s?
Khandro, //Whether I say "I believe it is raining in Paris", or I say "I believe it is not raining in Paris", depends on what information I have received from the weather-charts, the positive and negative have nothing to do with it, that is what I believe. Whether or not it actually IS raining there is, by the way, a separate issue.//
Your analogy (selectively?) ignores a third alternative.
There is a vast distinction between not believing in something (for which one has insufficient evidence to make a determination and draw a rational conclusion) and believing that something (ditto) is or isn't.
Hint: One is rational and one isn't. Can you guess which is which . . . and for extra points, which is the atheist?
