>>21122482UFO's were invented by ancient Egyptians so they could build the great pyramids. Egyptian royals realized that their tech was thousands of years ahead of its time, and that if these craft got into the wrong hands it could be very dangerous. They decided to keep the tech secret and pass the knowledge down via secret schools. This secret knowledge eventually reached Nikola Tesla, who was able to reverse engineer a major mechanism of UFOs, now known as the Tesla Coil. The Nazis used this to make foo fighters. The US eventually made their own as well, causing the famous Roswell crash. US UFOs are funded by DARPA and the Temple of Set, and the current reason why they've kept it all secret is that it could collapse the entire world economy. Aliens aren't real.
