In my opinion (yeah, I have one of those too. I'm sitting on it) each person has the privilege of believing it or not and no one will be able to change their minds no matter what 'evidence' or suppositions they provide.
I would very happily change my mind if I was provided with empirical evidence that I was wrong. In fact I would welcome people providing such evidence. If people choose not to change their mind after being presented with such evidence then they are fools. You are assuming that the default religious position of believing things despite evidence also applies to more rational individuals.
