We actually have an XFiles tier thread but no, only drones, military craft, meteors etc. In other words things people think are ayys. I'm not convinced a single UFO was extraterrestrial in origin however I do know saying so is a profoundly useful political tool to achieve various ends. I'm of the opposition to the alien hoax camp. If we needed unity there's plenty of other valid threats to use as outlined in the Iron Mountain report. I would prefer to use climate change over terrorism, ayys, and cybernetics among the others.
