What can science prove?

[Frank]

"Science proves what it believes," he says, as if science believes things. Dude, science is a methodology, a tool to be used. It does not have a brain, much less beliefs.

I'm not sure where the red herring is coming from (I never said or inferred science has a brain). You said:

"Science probabilifies, not proves"

I said, wrong, science can prove things (practically speaking). The examples I gave (computers, plastic, etc.) all rely on things proven by science. Sometimes science is only able to approximate, but not true in all cases (and you couched it as some sort of axiom).
