Looking to debate a Christian or atheist. You pick the topic (religious)

"You defining god as infinite is making it impossible for polytheism to exist [sic]. Yes that is illogical because polytheists believe that each deity has its own area of expertise." I went into detail why God has to be infinite. I assume what is my opponent's attempt to imagine a universe which is "created" at one point but still doesn't need a supernatural cause: "The cyclic universe theory is one that the universe creates its self, [sic] then is crushed under its own weight and collapses. This is not a supernatural cause, yet with the multi-verse theory a different universe could be created from this initial naturally created universe. This means that there is no Ultimate god as you suggested." First: the universe cannot create itself, because it would have had to be there before it existed to do so. A mother cannot give birth to herself for this very same reason. An event cannot logically be its own cause. Yes, this wouldn't be a supernatural cause (which I discriminated against in the 1st round), but it also isn't a logical cause. Oh, I see what Con is trying to do. The Universe creates itself, and then God creates a different universe from that self-created universe. This is sheer ridiculousness. If the god (or gods) isn't ultimate, then what is? A limited deity implies a greater deity. Know why? To distinguish between and limit them, they must be lacking, which means there must be an attribute that one does not possess. For us to know that there is an attribute that one does not possess, one of the other gods or this theoretical universe must possess that attribute and be the cause for this unevenness in attributes. That God would thereby be unlimited, and the ultimate cause. But, again, there is no evidence for multiple universes or anything in this theory. Therefore, even if my logic is somehow faulty inductive reasoning still stands against it. I wasn't expecting this issue to be brought up, to be honest! We are talking about OUR world, not some science fiction hypothetical. "A lot of Christians claim that the law of thermodynamics proves that the universe had to come from somewhere. They then struggle when told god had to come from somewhere saying that god is outside of the universe or is all powerful, 'the laws of the universe don"t apply to god they say.' Why do the laws of the universe have to apply to the creation of the universe? Everything that has a beginning has to have a cause. That is a law of logic that applies in all universes. The law of thermodynamics was just used to help you see that the universe did have a beginning. Although your claim that the universe was created by another universe complicates things, we can still say that for your universe to be the ultimate cause (requiring no cause of its own) would require it to be God, basically, infinite and without limits. A universe that does not run out of energy and has no beginning or end sounds not much like a universe (the universe would also have to be outside of space to have created another ex nihilo universe, another point fatal to your argument) and more and more like God. "The creation of the universe happened before the universe was created!" This is equivalent to saying I sat down before I sat down. No I didn't. The two events are actually one event, which means they happen at the same time. So you are incorrect. The creation of the universe happened when the universe was created. "I used your defined a creator god just no ultimate god. Checkmate." Don't say "checkmate" when you haven't even answered my arguments as to why we must have an Ultimate Cause, a being which possesses no potentiality and just actuality. I backed up my definition with evidence you never even considered. To conclude: my opponent is coming up with theories far more ridiculous than Christianity. Universes that create other universes. Universes without natural laws. Events that happen before they happen. Coalitions of limited deities working together. Your voting decision should not require much deliberation.
