Despite thousands of UFO sightings each year, there is no physical evidence to support the theory that they are spacecraft from other worlds. Powerful radars and telescopes have never observed extraterrestrial spacecraft, and most sightings are unreliable. Occam’s razor suggests that UFOs have other causes.
Since the first widely publicized UFO (unidentified flying object) incident, in Roswell, New Mexico on July 7, 1947, there have been thousands of UFO sightings a year. Since then, many have speculated that UFOs could be spacecraft used by extraterrestrials to visit Earth. A 2006 poll found that 24.6% of Americans agree or strongly agree that at least some UFOs are spaceships from other worlds.
Countering this 24.6%, however, is the absence of physical evidence. Despite decades of eyewitness accounts, including those of direct contact with extraterrestrials, no physical evidence has emerged. Not a single extraterrestrial machine, shred of extraterrestrial tissue, blob of paint, strand of extraterrestrial hair, or anything else that can be definitively put under a microscope and identified as not from Earth.
Low Earth orbit is constantly monitored by powerful radars and long-exposure space cameras. Tracking systems can detect anything larger than a golf ball. This is for the safety of those currently in space, as well as to protect against interpretations of falling space junk as enemy missiles. These space observation systems have never observed any extraterrestrial spacecraft. Astronomers, who observe the sky with high-power telescopes for a living, almost never observe unidentified flying objects.
UFO sightings take a marked jump after events that publicize other UFO sightings, such as the Roswell crash and movies like ET. This is similar to the “copycat” phenomenon seen when serial killer stories are on the national news. This data could be interpreted as an increase in the number of fictional sightings, while legitimate UFO sightings remain constant, but if so, why are there barely any stories of UFOs being sighted in America before WWII?
There are several unusually well corroborated cases of UFO sightings that could represent real boats. Mass sightings of silent, low-flying black triangles in 1989 and 1990 in Belgium were reported by hundreds of credible witnesses, as well as monitored via NATO radar and jet interceptors. This is an intriguing case, and there are others. However, the vast majority of UFO reports are very unreliable and the complete absence of physical evidence is overwhelming. Occam’s razor dictates that UFOs must be attributed to causes other than extraterrestrial visitation.
