Disproving Odin - An Experiment in arguing with a theist with Theist logic

[SteveII]

It stands to reason that if you define something you exclude everything else that does not meet that definition. Does this mean you are making some sort of claims about everything else that does not fit the definition or does it give the everything else so sort of status that it did not have before? No, that's silly. 

But here's the problem specifically with KCA.

The set of everything that begins to exist, contains everything we encounter in the universe.

Besides your god, what else is in the excluded set of things that do not begin to exist?

If your set of  exclusions (things that do not begin to exist) does not contain anything but your god, then you are smuggling the conclusion into the first premise.

A couple of things. One, an inductive argument is going to have, within its premises, mention of the subject (or in this case, it's negation) it is arguing for. There is no inherent logical problem nor is there a fallacy in this fact alone. I am not sure if you have a logical reason for thinking this important in this case or that you just think it should not happen in general. I would point you back to the All Men are Mortal...Socrates is Mortal argument. 

Two, not that it matters for the argument but a Platonist would say that a number of abstract objects would be included in the set of things that do not being to exists. Many mathematicians are Platonists. Another is people like Polymath and Grandizer think the universe exists infinitely in the past so did not begin to exist. It could also be another argument that there is nothing in that set. It's really not the question the argument was designed to analyze.
