If it were reasonable, then I could propose anything - for example, the flying spaghetti monster. Why don't you know about him? Because of a massive worldwide conspiracy.
Millions of reported sightings from all around the world, claims of abductions, cattle mutilations, Roswell, numerous military officials claims they exist, unexplained videos, photos, recorded broadcasts, secret military bases and cover up initiatives, and people on there deathbed who swear they landed but had to take an oath of secrecy.
Anecdotal evidence is not based on facts nor careful study. It's pseudoscience and to believe it is faulty logic.
