Are these paintings the world's oldest works of art? The paintings were found in an Indonesian cave, depict hunting scenes and feature human-like creatures pursuing animals. The art was discovered in 2017 on the island of Sulawesi. Scientists reported that uranium dating has placed the age of the paintings at 44,000 years old. However, the art's continued survival is still at risk, as microbes, water, smoke and salt threaten to destroy the ancient pieces.
