Of course, "why?" is a much misused word in supernaturalist apologetics. It's invariably erected as a shorthand for "who determined or decreed this?", in the hope that no one will notice that the whole idea of a "who" determining or decreeing the outcome is itself a gigantic blind assertion. All too frequently, however, when a child uses the word "Why?", he uses it (though not usually knowingly so) as a shorthand for "what reasons underpin this?", without any prior bias with respect to the nature of the underpinning reasons. Which is why I consider it an abuse to fob a child off with variations on the "Magic Man did it, now shut up" pseudo-answer.
As for the question of whether or not a god type entity exists, one statement we
can safely erect, is that it isn't any of the entities asserted to exist by any of our mythologies, because these entities are manifestly the products of ignorant, superstitious, pre-scientific minds with narrow, parochial imaginations. Any god type entity that
does actually exist, will almost certainly be radically different from anything we've experienced before, and will almost certainly falsify all of the mythologies humans have invented at a stroke, if it bothers to show itself someday. Indeed, if I were that entity, I'd try and find a way of answering the question once and for all, so that [1] I could turn round to humanity and say "Right, you have your answer, now stop the stupid bickering, and devote yourself to something useful, like particle physics or evolutionary biology", and [2] so that I could wipe the smirk off William Lane Craig's face.
