UFOs are real; that is, there are sightings of things that have not been identified. The whole thing is  based on a sighting by Kenneth Arnold in 1947 that was probably a flight of pelicans and 50s science fiction movies. Arnold described a flight of wedge-shaped objects that flew like saucers skimmed over water. The newspapers got it wrong and called them “flying saucers”, and everyone started seeing saucers and discs. Tropes like missing time, buried memories and alien implants all appeared in 50s films like INVADERS FROM MARS and KILLERS FROM SPACE before anybody reported them in real life; and abductees reported boarding the ship by a ramp, like in the movies, but once STAR TREK came on, they reported being beamed aboard. The people who made the first crop circles admitted it was a hoax. Dr Simon, who brought out abductees Betty and Barney Hills’ abduction story under hypnosis, diagnosed that those were not real memories but a delusion brought on by Betty’s lifelong obsession with UFOs and Barney’s submissiveness to her will. UFOlogists who have brought out other abduction memories don’t tell us that hypnosis does not bring out truth, but only what the hypnotized person thinks the hypnotist wants to hear.  

UFO doesn’t mean alien spaceship; it only means unidentified. Every UFO sighting that has been properly investigated has proved to atmospheric phenomena like lenticular clouds (below), misidentified aircraft, drones, birds, stars, planets, reflections of ground lights, mirages or outright hoaxes. In several cases where clear photos of flying saucers were produced, the miniature models the photographer used were found. There is a known condition called sleep paralysis that causes people to wake unable to move with a strong feeling of being watched; in the middle ages this was blamed on witches - now it’s aliens.

UFOlogists - who have never studied a UFO, only witnesses' stories - have come up with a clever excuse for not having any proof (NOTE: stories, reports, anecdotes, testimony and hearsay are not proof): the government is hiding the truth. Of course they have no proof that the government is hiding anything either.

Think about it. If UFOlogists actually believe in aliens, why haven’t they ever tried to prove it? Have repeat abductees wear a wire. Set up a broadcast signal in their homes such that if the alarm stops, they’d know that aliens were interfering with electronics. Have response teams ready to catch the aliens in the act. They don’t, because they know nothing would happen and they’d be proven wrong.

There is no reason to fear aliens once you understand that they are not real.
