[Witcher] How did humanity thrive before witchers?

Were regular humans, in large numbers, able to kill monsters near towns and villages? Did humans actively remove monsters at a location where they wanted to build a settlement? Do monsters generally avoid large groups of traveling humans? Are monsters afraid of humans the same way animals larger than humans tend to be?

Witchers are great at what they do and specialized, but knights, sorcerers, and monster hunters can typically do the same job when not preoccupied with war. The games do a disservice to the books in exchange for a more entertaining experience for the player - monsters in the witcherverse are few and far between typically, with the animalistic ones avoiding humans and the ones smart enough to be a large-scale threat realized that it’s better to join humans than beat them. The reality is that witchers *aren’t needed* anymore for the most part.

Humans were so successful before witchers because they are innovative and reproduce quickly in large numbers.
