How can it be that all the human languages form logical grammar structures without anyone defining them from the first place?

Question

It seems like grammar rules just form up on their own and no language is a “mess”, how can it be?

Answer 1

Well because the rules are so different from language to language. It seems humans need some sort of basic structure to how they speak, in order to best be understood. But there is no universal structure that languages are required to have. There is logic to each language, but the logic changes depending on the language.
