What in aggregate behavior can you provide objective proof of yourself (nothing)

What in aggregate behavior can you provide objective proof of yourself (nothing). What can we EXPLAIN using the empirical evidence of behavior, and the behavioral science that causes it?

Asking for proof is evidence of incompetence. Asking for explanation requires you have requisite knowledge to understand it.

So if you (a) ask for proof and in doing so (b) demonstrate you lack the requisite knowledge to hold an opinion, the why do you assume your opinion is worth anything whatsoever to yourself or anyone else?
