The pyramids of Egypt are staggeringly ancient. By the time of Cleopatra, they were already thousands of years old. But new research claims that another pyramid might have them all beat, potentially rewriting the history of human civilization. 

A team of researchers say in a new study that Gunung Padang, a pyramid in Indonesia, is at least 16,000 years old, roughly 10,000 years older than the pyramid of Djoser in Egypt, long thought to be the world’s oldest.
