I believe [philosophically] you got it wrong here.
Your philosophical stance here is Philosophical Realism.
Realism (in philosophy) about a given object is the view that this object exists in reality independently of our conceptual scheme. In philosophical terms, these objects are ontologically independent of someone’s conceptual scheme, perceptions, linguistic practices, beliefs, etc.
Realists tend to believe that whatever we believe now is only an approximation of reality but that the accuracy and fullness of understanding can be improved.[2] In some contexts, realism is contrasted with idealism. Today it is more usually contrasted with anti-realism, for example in the philosophy of science.

I agree with the theories of Philosophical Anti-Realism, i,e, Philosophical Realism is not tenable, there are no thing-in-itself that is independent of the human conditions.
It is quite a long story to argue on this issue but your views here are not tenable.
Science merely simulates by analysis of what’s already there.
Ontology is a late development, after the pre conscious made the leap to the existential choice by using acceptabce/rejection as a survival mechanism. Ontology, or The basic logic of exclusion by contradiction has the above sourced dynamic characteristics.Now the point is, that God in essence, therefore, is not merely a conceptual ontological product. but a staged effect of an existential dynamics, a primordial base of freedom anchored in the choice between acceptance and rejection.
I can elaborate on this kater, but depressing here would needlessly cloud the issue at hand.So the argument You bring forward about the exclusive ontologocally psychological defense, fails on the face of it.
I had argued,
Me:The only valid reason and usefulness of ‘God exists’ is for psychological reasons to soothe the terrible rising and pulsating angst.
No matter how you argue, you need to prove God exists in reality.
You have not done that at all but merely making statements, producing no arguments and merely wishing God exists.
Have you ever consider the psychological reasons why you need and must believe in a God?
For a theist is not easy to look at alternative approaches as it can be very painful to deliberate on that ‘divorce’ from theism. But for philosophical sake, it is wiser to learn of other alternatives to deal with that inherent existential crisis.
As a guide, note the philosophies of Buddhism which adopts a psychological approach to deal with that inherent existential crisis.
