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

Grammar rules are language specific, not universal.

And language without grammar rules is incomprehensible, so in order for language to accomplish anything meaningful beyond communication of vague concepts, grammar is absolutely necessary.

“Og and I saw 15 buffalo, two moose, and a rockslide today” communicates a very complex story. Without grammar rules, it becomes meaningless and easy to misunderstand.

“Buffalo saw Og I moose and two rockslide a today and” is the exact same sentence without grammar rules. How could you possibly parse what this person means, even though the words in the sentence are exactly the same?

The answer is you can’t.

So grammar evolved with language because language is next to useless without it.
