The most interesting part of the movie, I found, was when they were sitting on the park bench, and he was trying to explain to her (in vain) about metaphor, without actually having a means of explaining (didn't have the words). "God" is metaphor, both in symbol (being) and use (reality). A world with "atheistic worldview" would be a world devoid of metaphor, because with the inclusion of metaphor it would be necessary (as Voltaire pointed out) to invent "God".Funny movie with an interesting premise (started out funny anyway). But, in what way would someone holding an "atheistic worldview" relate to that movie in your view?
