Using your own argument, that would mean that 'god the father' could not exist since he would first need to make the universe and then his son (to be a father). Regardless, I can equally assert that spaghetti exists only because the FSM created it in his own image, the same way christians insist they are created in god's image. No more contradiction. Bottom line is, that when it comes to god, there's no (scientific) way to (prove or) disprove it's existance, regardless of which god(s) your are talking about, which is the whole premise behind Russell's teapot. (Just for sake of argument, you cannot view the entire solar system through the Hubble telescope at once, nevermind a teapot god that may wish to remain undiscovered.)
With all due respect, this discussion only digressed somewhat to semantics since you were implying these terms mean something they do not. I am not arbitrarily saying anything and have already linked sources to the validity my assertions. If you insist you can arbitrarily give words their meanings, then I suppose I have nothing left say.
I'm hardly arbitrarily giving words meaning when I quote the definition of 'god' from a dictionary reference and then apply that definition in context. But, then again, I'm not attempting to prove the existence of God, I'm simply arguing that the FSM is a bad analogy. It's a bad analogy specifically because analogies only work if the characteristics of the things being compared are similar.
Am I missing the point of the analogy? I thought these things were always brought up in the same abstract vein; that is, you can't prove god exists any more than you can disprove there is a teapot/FSM/whatever-else. The analogy isn't about which mythical creature exists or what properties and powers it may or may not have, it's about the existence of
period. From this view, I think the analogy is fine.
