Humanity Lived Underground for 500 Years | Sci-Fi Documentary

What if an entire civilization agreed to live underground for 500 years because they believed that one day they would be allowed to return to Paradise? Deep beneath the surface, more than 10,000 people live inside a self-sufficient underground city where every gram of food, every liter of water and every unit of energy is carefully controlled. For generations, they have followed the Doctrine of the Great Rest: humanity once destroyed the Earth, and living underground is the price they must pay for their ancestors' mistakes. Those who complete a lifetime of sacrifice are promised the ultimate reward: **the Ascension** — a return to the restored world above. But after more than five centuries, small inconsistencies begin to appear in the system. And behind the promise of Paradise lies a truth that could destroy the civilization the lie was created to protect. 👉 On **History of the Future**, you'll find science-fiction documentaries narrated as if they really happened.
