Where does your trust in physics come from?

Qe often say "physicis proves.." "logic shows..." "science shows.." and so on The reason—whatever it may be—that we believe "Physics offers true X(s)" and "Neuroscience shows true Y(s)" is:

A) something that Physics itself offers and Neuroscience itself shows etc or B) something (an intuition, a profound phenomenological experience) deeply ingrained in your cognition ?

If it is A), can wr present and expose that reason within a rigorous physical and neuroscientific framework? If it is B), why do we attempt to deny and destroy these "deeply ingrained truths" when our very trust in Physics and Neuroscience originates precisely from them?
