We humans invented everything.
As in everything, as in I mean everything.
Plants aren´t called plants because their real name is plants.
We named them.
We have named every single little piece of living thing over the face of the Earth.
And this only because we communicate because it is in our born instinct.
We humans understood that we had the ability to communicate and we decided to name everything.
But we actually invented everything.
So when we think of words we think of how we memorized every word, even when we forget their names we replace them with something different.
So under everything we created them, it´s not like someone told us the way it was.
We, as in someone else, did it.
