ELI5: Since most animals have some sounds that they can make and most members of a single species make the same sounds, why do humans have so many very different languages and is there a single language that is the most natural for humans to speak?

Your question sort of answers itself.  Humans use the same “library” of sounds to construct many different languages.  In that way, we are the same as animals.

We know that birds and whales can learn different songs depending on the region where they live.  That would be analogous to different human languages.

Is there a human language that preferentially uses the “best” sounds or the fewest sounds?  That is difficult to answer definitively.
