rodog, I think this boils down to semantics.
You use the word proof in another meaning than me. What I think you mean with it is something like "very accurate", I use it in the original scientific meaning.
A real proof can almost never happen in sciences outside of mathematics.
Proof is not a matter of degree of accuracy.
You can google the definitions for yourself.
I have already addressed all your other points, just read it there, I will not repeat it again.
