@igm,
that's a very good subject and I have often thought about it. first of all, I am atheist but, if someone is capable to provide an argument reasonable of the contrary, it would be close minded refusing to listen.
I don't thing that there is some thing that would make me change my mind and I am not eager to wait for it BUT, if it should happen I don't see why reject it.
The refusal without giving the option to evaluate the subject would be just like the catholic religion that suggest you to dismiss any argument if they are not pro-religion
