First order logic, set theory and God

" ... to explain how the universe was created by something external to it."


That's an ill-founded claim. I, neither Hatcher, have stated that the cause was external to V(universe or reality), if you had read carefully, you'd see that G is either a component or a subsystem of V and hence internal (part of) to V, while being different from V itself; G ≠ V. On that basis, your idea of a "larger external universe" containing another universe - is bogus, nonsensical and to be categorically dismissed.

Ah right that makes a lot more sense.

The universe was created by something inside the universe before the universe existed.

Got it!

The reason why casaulity is used in hatcher's proof is because it attempts to articulate the ultimate origin of existence. Thermodynamics doesn't. All it does is it explains the entropy of thermal energy and its conservation within the universe, and for that reason it falls flat at demonstrating the existence of a metaphysical reality.

There is no evidence for a metaphysical reality. Nor is there any reason to suggest that one exists.

Thermodynamics on the other hand explains why everything within the universe has formed the way it has.

So if you are going to cherry pick any thing from inside the universe to explain what was happening before its existence, why pick a ' logical and relational principle' rather than a universal physical law?
