I don't have anything to offer as a religious individual, because I'm not one. However, it hardly seems logical or practical to inquire what the sciences have to offer and require that only non-scientists speak to this (or that only religious scientists do). Also, as the OP asks about God (not religion or even religions which have gods, but "G"od), it isn't really a religious topic. It concerns what the sciences have to say about one aspect of a tiny, tiny minority of religions so different from religions in general that they didn't exist until a fairly recently in human history.
