I am a theist, what do you think of my proof for God existing?

[pocaracas]

Next, I have not seen any proof from any of you, dear atheist colleagues here, of anything to be existing at all, from concept to object

Of course not.
That's not how things work.

We discover objects in reality and then form an abstract concept of it in our minds.
The nose was in existence far before any human gave it a description.
