By Copenhagen interpretation I assume that you’re referring to the 1935 paper by Schrodinger and Einstein from which the Schrodinger’s Cat illustration of what he and Einstein had issues with quantum mechanics about.
I don’t see where you’re going with this though.

Schrödinger actually came up with the cat example in opposition to Bohr et all -- the idea was that the box was such an absurd idea it would make the Copenhagen interpretation seem silly. it does however, turn out to be true. it's how you test whether bombs are duds or not, for example, without blowing them up. it works.
the cat is neither dead nor alive, nor both nor neither, but doesn't really exist at all outside of probability space, until it is observed. existence is something
done to a 'something' rather than an inherent quality of it; it's dependent on an outside observer ((by Him all things consist))
so how does the universe exist? who observes all the universe, over all time? if there was a 'big bang' of a singularity within which all space and time consisted in a single point, someone had to observe that, else it couldn't exist. someone who is not part of the created universe, unbound by & separate from space, time, matter and energy. and that observer gives all that is existence by regarding it -- speaking it, you might say.
Heisenberg considered consciousness a fundamental of the universe; there has to be a consciousness that observes the universe in order for the universe to exist. so -- quantum physics reveals the existence of God; it demands it.
in an algebraic sense another instance of this proof is Gödel's incompleteness theorem applied to the universe as a time-sequenced complex system: there has to be something unprovable in the universe as a logical system without something outside the universe; an axiom. the universe itself cannot explain the universe; there must be something outside the universe: creation demands an uncreated Creator ((and this isn't saying it circularly)), which is to say, Colossians 1:16 -- by Him all things were created, and He is not created, but He is "I AM THAT I AM" -- the eternally self-existing God, the 'First Cause'
