Unidentified flying Object (UFO) is any object or light in the sky that cannot be immediately explained by the observer. Sightings of unusual aerial phenomena date back to ancient times, but UFOs (sometimes called flying saucers) became widely discussed only after the fist widely publicized American sighting in 1947. Many thousands of such observations have since been reported worldwide.
At least 90 per cent of UFO sightings can be identified as conventional objects, although time-consuming investigations are often necessary for such identification. UFOs most often turn out to be bright planets or stars, aircraft, birds, balloons, kites, aerial flares, peculiar clouds, meteors, and satellites. The remaining sightings can probably be attributed to other mistaken sightings o to inaccurate reporting, hoaxes, or delusions, although to disprove all claims made about UFOs is impossible.
From 1947 to 1969 the United States Air Force (USAF), investigated UFOs as a possible threat to national security. A total of 12,618 reports were received, of which 701 reports, or 5.6 percent, were listed as unexplained. The USAF concluded that “no UFO reported, investigated, and evaluated by the Air Force has ever given any indication of threat to out national security”.
Some people nevertheless believe that UFOs are extraterrestrial spacecraft, even though no scientifically valid evidence supports that belief. The possibility of extraterrestrial civilizations is not the stumbling block; most scientists’ grant that intelligent life may well exists elsewhere in the universe. A fully convincing UFO photograph of a craft-like object has yet to be taken, however, and the scientific method requires that highly speculative explanations should not be adopted unless all of the more ordinary explanations can be ruled out.
Unidentified flying objects and aliens can be proven through eyewitness accounts or encounters. One of the most common cases would be the case of the Hill’s. Returning to N.H., the Hill’s had notice a strange light in the sky. Barney stopped the car, went out to observe the moving lights. He came to the conclusion of the lights being an airplane, a star or a plant. As they continued their ride the light remained with them. That took away the idea that the object was a star or a planet. When the object drew closer, Betty looks at it and saw the shape of a disc like figure. They took a way the idea of it being an airplane, so they got out of the car to get a better look. At one point, the object got so close that Barney could see several beings staring down a pond near them. He lost control and shouted out, “They are going to capture us”. They raced back to the car and took off unable to explain what had just happened. The next thing that happened was that they heard a couple of beeps like a microwave oven going off. The next day Barney had noticed some unexplained blotches on the car. Later on that day the Hill’s realized they could not account for two hours and thirty-five miles of their journey. They begin to have stress problems. They could not explain why Betty was having strange dreams about being taken into a room and being looked at by strange little beings. After that they begin to see many doctors. After a while their story had been put together in the little pieces that they had been telling it in. The story that was formed was that how their car was topped by a group of strange looking men with pear shape heads and large wrapped around eyes. Then by force they were carried on, to the ship on to separate rooms. Then they were given different test. Some of the test includes taking skin and hair samples. While inside Betty remember seeing a star map. Later on the map was identified as the Zeta Reticule system. This proves that UFO’s and aliens are real because when explaining what had happen they were both in separate rooms under hypnotist ion. And also there was no one to explain the lost in the time or the marks on the body and the car.
UFO enthusiasts persist, however, and some people even claim to have been abducted and taken aboard UFOs. No one has produced scientifically acceptable proof of these claims.
