There will never be a point at which science could confirm nor deny the existence of any divine beings. while we may eventually think we can answer everything about the universe, that does not imply that some god put it there to begin with or is still altering the effects, which we label as laws of nature.

Because of that I don't think I ever will believe in their existence, but I think that the purpose of religion lately has become more of a social support system than a teaching tool of why things are.
Without religion though we would have been hard pressed to form the social moral systems we have now, such as being nice to others etc, as we'd have nothing to reason as to WHY it is right to act in such a way and wrong to not.
