There is almost nothing as thrilling as seeing art made by our early human ancestors. The recent discovery of (very) early art in Indonesia is radically expanding the way that we understand the earliest human attempts to make art. The earliest of these images are 40,000 years old. This puts them at the earliest edges of European cave art, like that at the Chauvet Cave in France. The earliest images at Maros in Indonesia were made when one of our ancestors put their hand on the wall of a cave and sprayed paint over it. The result was a negative hand print.
