I agree with Karl Popper's idea that falsifiability is required of a scientific theory. On the other hand, science is not the only thing that humans find interesting, and it is not even the only way to acquire knowledge.

For example: "I think therefore I am" is a famous example of knowledge that we can all obtain by non-scientific means. There is also the knowledge of what being in love feels like, or how sardines taste like -- both not obtained through the scientific method.

I guess is possible to only find science interesting and nothing else, but that would make you a very unusual human being.
