God, as usually described transcends physics. Hence metaphysics.
In order to exist at all, time is required.
True for finite, changing, material existence. Not true for infinite, non-material. In theology, 'eternal' means "existing outside all relations of time; not subject to change."
You are making basic category errors in addition to gross reductionism.
That is not a valid conclusion. You asked who is my teacher and I told you.
"God, as usually described transcends physics. Hence metaphysics."
The modern function of "transcend" is to remove a real object, or concept from rational evaluation. The word applied previously in speculations, with very little knowledge and understanding of reality. It was used to postulate and construct models of existence w/o knowing and understanding evidence provides.
Re: "In order to exist at all, time is required.

It is true for all things that are real. These are terms that were used, but never understood before. They are now. All things in any world have an underlying physics. There are no such things as "supernatural". The word material refers to the physics of this world. There is no such thing as non-material real objects. Even a thought depends on an underlying physics for it's existence.
"In theology, 'eternal' means "existing outside all relations of time; not subject to change."
There's 2 claims made here. The first is simply a claim. That claim consists of a proposition, that can be proved false, as I did. Time is a measure of existence. If there is no time, there is no measure, so "eternal" is meaningless and time = 0. Not subject to change could mean many things. It would be better to say, that God is persistent and consistent for all eternity.
