15The Black Knight
Back in 1957, one of the first human-made satellites was launched into space. Since then, over 300 satellites have followed suit. These satellites were engineered to give us Earthlings access to things like telephones, internet, cable, and weather forecasts — which we are forever grateful for. However, there is one
strange satellite circulating Earth that is estimated to have been in orbit for thousands of years. Obviously, it was not launched by humans themselves, as there was no access to such technologies a century ago, let alone thousands of years ago. When NASA first noticed the strange black satellite, they didn't know what to make of it, and to be frank, they still don't know. The ancient satellite has been given the name The Black Knight, and remains both a mystery and a conspiracy to us Earthlings, but not to the entities who set it up.
