Question

why are sets so important?

Answer 1

Sets are important because they encode a totality of information of a certain kind, in a more formal manner. Set Theory studies 'invariances' of sets. That is, stuff on what is in the set is not as much about set theory, since such objects come from other parts of mathematics.
