Possibly, but it is the most ancient cave paintings yet found. https://en.wikipedia.org/wiki/Magura_Cave#Paintings 8000-10000 years ago.

The area that these things were found is nearby the Danube river and rivers like her are ancient, far more than 10,000 years old. The danube follows a very long, very flat path out to the black sea and it is unlikely anything near it is recent vulcanism, so the caves could well be excavated by humans, originally, or at least, one of the refuges after they received the warning to hide there by the "angels".
