No line of reasoning is broken until it is demonstrated to be illogical or wrong.
Saying that it could be something else breaks no reasoning whatsoever.
*facepalm* You really have no clue at all, do you?
If all you want to do is argue that your version of god is a
possibility, then you're wasting your time, because as long as it's
unfalsifiable, it must also be
possible, which applies to endless concepts of god(s). I'm not aware of anybody here who has argued that all versions of god(s) are impossible.
If, on the other hand, you want to construct a
logical argument for your god, you either need a deductive argument or an inductive (probabilistic) one.
If you're trying to do a deduction, then it must be
impossible for your premises to be true and the conclusion to be false (
validity) and also your premises must be accepted as true (
soundness). Hence, if there are other possibilities in any of your steps, it becomes
invalid.
Even if you're trying to an inductive argument and you're into the territory of blind guesses, as everybody is with regard to the basis of existence, then one is as good as the other, so the existence of other guesses also undermine your position.
But I'm afraid your logical error is that you want the universe to be it's own explanation and want an external explanation as well.
No, I don't. For fuck's sake, close down the straw man factory you seem to have running night and day, and pay some attention to what I've
actually said.
As I keep on saying, you need to define your notion of "God", then present your premises, then a deductive or inductive argument.
