Although interestingly I suggest that many and indeed most people don't require science to validate their beliefs. So many things that "science" has held to be true (from a flat earth to the safety of Thalidamide) have subsequently been proven to be false that there is some argument to say that accepted scientific theory is a belief system the same as any other - with schisms and sects and camps that contradict one another. And like many other belief systems it feels the need to seek converts and preach its "one true way".
Believe whatever you wish is my view - provided it hurts no-one else. We all have our mantras (E=MC2), our high priests (Nobel Laureats) our heretics (climate change deniers, string theorists etc.) and our catherdals (Cern). Unless you have repeated all scientific research personally, at days end it is still an act of faith that what it reports is true. Indeed there have been some notable reported cases where research results have been "de-bunked".
So whatever you believe - science, superstition, or religion, ultimately you are putting your faith in something else that you personally believe to be true but cannot, ultimately, know to be true.

Well, scientists
never believed the Earth was flat.
Eratosthenes calculated its circumference to a remarkable degree of accuracy in the 3rd century BCE.
It's true that science is far from perfect, and doesn't always get things right first time. The difference between science and all the other approaches is that science has an in-built mechanism for finding out when things go wrong and correcting them. Which is how we now know that thalidomide has serious side-effects...
You cannot
ultimately know
anything to be
absolutely true,
ever. The best you can manage is to know what seems to be true, given the best currently available information and understanding. Truth is a moving target. But only science even bothers to ask whether we're getting closer to it - all the alternatives simply assert their version of the "truth" and then change the subject.
And of course, the other great thing about science is that it can produce
useful results. For example, did you know that GPS only works because we understand the General Theory of Relativity? So given that it clearly
does work, the theory can't be
too far wrong.
