The term Universe is a collective term only. There is no actual universe based on universal particles. Does not exist.

Said differently, Gödel's Incompleteness Theorems show that there is no overarching framework.

So, if we use a framework, then we can never take that framework to the top level of the universe and have that be a completeness.

A completeness is found only inside each framework, based on the axioms of that framework.

In other words, if we use the term God, then all we need to do is find a word we understand to be true to make God be true as well.

For instance, the word Energy can be used for all that exists (space is not a physical entity, so we have something extra next to Energy as well that is not Energy).

We can state that God = Energy, and voila we have the evidence that God is real because Energy is real. It is actually super simple.

But the next question is then if we can find unification in Energy, and the answer is No. Planet Earth is floating through space in quite the opposite direction from a planet in a galaxy moving in the opposite direction as our Milky Way. So, Energy is not unified at the universal level, which is fine because we already stated that there is no universal framework based on universal particles.

That means that when we use the term God, then we must abide to the underlying reality of the axioms in which the word God is real.

That means that God can be real, but we cannot use the term willy-nilly.
