If there was a global flood the cave paintings at Chauvet 32,000 BP, Lascaux 17,000 BP and the carvings and artifacts at Le Portel 11,00 BP weathered it quite well. On a side note there are no dinosaurs depicted in any of the individual pieces or panels in the caves.
As long as you have the wrong world view you will not understand that these happened after the Flood. The caves you are discussing did not exist prior to the Flood.
