Handprints found on cave walls in Indonesia may be the oldest rock art ever studied, dating back at least 67,800 years. Indonesian and Australian researchers discovered the prints on the island of Sulawesi inside limestone caves. The images were made by placing hands on the wall and blowing pigment around them. Some fingertips were shaped with care, showing clear planning. Scientists studied mineral layers on top of the paintings to measure age. The results showed the prints are very old and important for the study of early art.

Researchers said the artwork shows that people on the island made art long before written history. The study was published in a scientific journal and raised questions about the artists. The prints may belong to Denisovans or to early modern humans traveling through the area. Other drawings nearby, such as animals and people, were made much later. Scientists believe older art may still be hidden on nearby islands. Future research may help explain how early people began to make art and share creative traditions.
