These stencils and paintings, discovered decades ago in prehistoric caves in Indonesia, have just been confirmed as some of the oldest in the world. Scientists now think they were made around 40,000 years ago.

A painting of a babirusa (also known as a pig-deer), was dated to at least 35,400 years ago.

The oldest image is at least 39,900 years old, making it the oldest known hand stencil in the world.
