From a scientific point of view, of course I care for the god hypothesis. Its existence and nature are facts about our universe that are definitely worth knowing. But since we have absolutely no hard evidence supporting the existence of any god, anything we say about it and its nature must be either an uneducated guess, or just shamelessly made up.
From my personal perspective, however, should I care about god at all? Would it change anything in my life? Would I become a better person, if I just started believing against all reason?
