The Hidden Empire (S11E09)

Ancient Astronaut theorists propose that signs of alien contact can be found throughout the globe, with some of the most intriguing evidence located in the remote landscapes of China. As the birthplace of one of humanity's earliest and most impactful civilizations, China has contributed groundbreaking inventions like gunpowder, paper, and the compass, which are foundational to modern society. However, its historical stance on isolationism, exemplified by the Great Wall and the contemporary "Great Firewall," has restricted the flow of people and information. Despite this secrecy, emerging evidence hints that extraterrestrial beings may have interacted with humanity in the past—and possibly still do, blending into our world.
