God's God

The same logic can apply both ways dude. You are running off on a red-herring. If "God" (whatever that means) can "be his own cause of his own existence" then so can the global universe (i.e. - all of existence itself). It is the fallacy of Special Pleading to try and attribute something to your deity (by arbitrary definition) that cannot also be said of all physical existence itself. The reasoning is just fine. It is your reasoning that is flawed.

Again, you cannot just define your deity into existence by giving it arbitrary secondary characteristics. Talk about circles. This is exactly why I stated it as such in the OP.
