Belief

[theVOID]

Nature as you have described here is incompatible with the other picture of "nature" and "super-nature"; Their boundaries are usually defined by the presence or lack of material interaction.

Interesting, so that would mean certain aspects of the universe could potentially be "unnatural" as well.

Only if by unnatural you mean "not of the material reality" or something to that effect. You can't so easily use terms like "unnatural" as they occur in one model of reality and then expect the other models to conform, what you would consider "unnatural" in the other model might simply be "immaterial".

You assume all things that exist (are things) are products of a creation.

Not quite, nothing still exists (but by nothing I should have referenced the nothing of physics). True nonetheless though. It's a fallacious argument, the only time I've actually used it was to show the flawed reasoning behind the uncreated creator/first cause scenario.

Lets make a distinction here and call the Physics "nothing" the Vacuum. They are entirely different concepts. I don't know if your argument still works as a proof that "god" does not exit, but if we make the distinction then we have:

1. The Vacuum is not created (likely true).
2. "Something" is created (things that are not the vacuum cannot create themselves).
3. Therefore the uncreated creator is (probably) the Vacuum.

It seems to turn it into a positive argument for creation out of vacuum energy.

The burden of proof is yours

And I've gotten nowhere in disproving leprechauns, wendigos, furies, wizards, goblins, invisible flying ninja robot monkeys, or Darth Vader. Nor have I proven that I am indeed, not God. What burdens I have...

Don't make claims positive claims you can't justify?
