This is a tricky distinction where this may be true of all specific individual humans, but not of humanity. At some point, language and art didn't exist, and humanity invented those things. We didn't mimic some other civilization that did it first.
I don't know that this distinction matters, but it is real. Even on an individual level, if you raise a child in complete isolation from history and teach them no language or art, they'll still form thoughts, have feelings, and develop means by which to communicate those.
I think this is the big open question of evolution as a whole, and language and art can be seen as the evolution of ideas/memes as Dawkin wrote about in the Selfish Gene. Were these developments sufficiently iterative, or was there some great leap that came out of nowhere? Was the wing merely just a stump on an animal that allowed it to leap tree to tree a foot further, or was it some process unknown to us? Was art just a splatter of blood on a cave that looked like a face to our brain’s face neural network, or did some inventive genius paint a mosaic when nothing else was ever on the cave wall?
