Welcome back Rabbit - nice to see you! 
No one said anything about final proof. Quite the opposite. Man made definitions can be perfect to the standard man can set them. We're not talking about a definition from anyone else's perspective, for then you would be right - how could we know?
You said: "It truly leaves without explanation how imperfect beings with imperfect knowledge and imperfect faculties could ever lead to something perfect in an absolute sense."
Which is what the theological argument postulates.. perfection comes from the source. The source has to be the most perfect for everything to have emanated from it. Imperfection doesn't lead to perfection. Perfection leads to imperfection.
I agree, we can see how theology has evolved.
