He is making an epistemic argument, and epistemology is a part of proper science, though not of scientism, which is what you are bringing.
Binary is not the only form of logic available, but it is the most popular in discussions of the unknown.
> Your original point says very little.
You are literally mixing up subjective and objective.
> Yes, science acknowledges that you can never 100% say "X causes Y".
Careful though: science also does the opposite. Do you know why? Because science is composed of scientists, and scientists are Humans, and Humans are famously unable to distinguish between facts and their opinion of what is a fact. In fact, doing so is almost always inappropriate, and socially punished.
> Science is about...
It may intend to aspire to that, but what it is, is what it is. And what that is, comprehensively, is unknown, because it is unknowable. But we do know portions of what it is: there's the part you said, but there is also deceit, hyperbole, delusion, etc...again, because it is composed of Humans, and this is how Humans are. In my experience, all Humans oppose extreme correctness, I have never met a single one who does not.
