I did not mention or claim proof or proves. Only math can prove anything, because it has formal methods (inference rules) applied to assumptions (axioms). The proof is always contingent on the rules and the axioms.

Science approaches truth as an asymptote, which gets ever closer, but can never be reached (see Zeno). Science denies the possibility of claiming truth. Every theory is open to falsification, then revision, qualification or abandonment.

Science is the rigorous and rational application of doubt.

It's doubt all the way down.

Doubt is the only truth.
