According to Yuval Harari, the most successful story ever invented by humans is money. He explains that money is a fictional story that everyone believes in, which allows humans to cooperate flexibly and on a large scale. This shared belief in money enables complex economic systems and widespread collaboration, setting humans apart and driving their success as a species. Harari points out that money has no objective value on its own but works because people collectively agree to believe in it, making it a uniquely powerful and successful invented story.
