There does seem to be a lot of confusion about the distinction between nothing having absolute certainty and everything being equally uncertain. This leads to a misunderstanding of the role of reasoned hypothesis vs. blind faith. It isn't about always having the correct conclusions, but to have a process in place that allows for continual, systematic revision of knowledge. I recently came across this quote by Carl Sagan that should provide clarity for people who don't see these distinctions.
"Science is more than a body of knowledge. It is a way of thinking; a way of skeptically interrogating the universe with a fine understanding of human fallibility. If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then, we are up for grabs for the next charlatan (political or religious) who comes rambling along.”
