Something that drives me crazy about most people is that they have a need to "pigeon hole" thoughts and beliefs. Questions focus on "what religion are you," or "do you believe in god," is part of the need people have to position you somewhere in their minds.
That being said, I think the third alternative, at least for me, is to acknowledge that that is an interesting question. However, I am not prepared to answer it just yet. But, thank you very much for asking.
