I agree with you in the sense that, any God that does not contain the concepts of a creator and trinity, would disappear with the believer.
But suppose that the words God or YHWH aka Yahweh, Allah, etc. represents the “creator” of the “trinity” of space, mass, and energy. (Matter can not exist without the three ingredients of space, mass, and energy, that is why I refer to it as a trinity.)
If that is the case, then it would not matter even if the whole Earth and everything on it would be destroyed or totally disappear, the “trinity” of “space, mass and energy” would still remain in the rest of the universe. And the (whatever name) creator that caused the said “trinity” to come into existence would still be there.
My opinion.
