Sure, we simply haven't found earlier evidence.
Or, alternatively, guys from outerspace did the drawings, or..... there are many, many possibilities. At the moment, though, we have only this cave.
I objected to the comment re:
Art hit the ground running. There appear to be no amateur, tenative, halting steps ~ there was no art, and then there was.Given the scarcity of the ancient rock art, I think its a little early (no pun intended) to make any firm statements on the course of its development.This is a result of some sort of genetic change that occurred in Europe first.
What would you posit for a genetic change? We have modern humans some 160k or more years ago. I know there were two groups in this part of Europe at some 30k. What are you thinking for the genetic change.

Notice that top level dancers in every society appear to have a sense of position similar to that of top level basketball players. Not all of us have that ~ actually, almost none of us do.
Then there are the musicians ~
