UFO or ALIENS is Real ??

Unidentified flying object ( UFO ) Aliens

Unidentified flying object (commonly abbreviated as UFO or U.F.O.) is the popular term for any apparent aerial phenomenon whose cause cannot identified. The term Unidentified Flying Object has been in use by the United States Air Force from at least as early as February 1948 [1] where it was defined in terms of descriptive characteristics such as shape, speed and manoeuvrability. However in 1952 the USAF more formally defined UFOs as those objects that remain unidentified after scrutiny by expert investigators,[2] though today the term UFO is colloquially used to refer to any unidentifiable sighting regardless of whether it has been investigated. Another widely known acronym for UFO in Spanish, French, Portuguese and Italian is OVNI (Objeto Volador No Identificado, with variant regional spellings). Some investigators now prefer to use the broader term unidentified aerial phenomenon (or UAP), to avoid the confusion and speculative associations that have become attached to UFO.[3]
Though the term ExtraTerrestrial Vehicle (ETV) is used for only a small subset of UFO studies [4] for many people the term UFO is positively associated with alien spacecraft and many discussions of UFOs revolve around this presumption.[5]. While serious UFO researchers maintain that Extraterrestrial Intelligence (ETI) as a cause for UFOs remains a speculative hypothesis only, nevertheless many UFO enthusiasts, contactees, and devotees have created organizations and religions (for example The Church of Scientology) that have adopted extraterrestrial themes. It is therefore fair to state that in general the extraterrestrial UFO concept has evolved into a prominent mythos in modern culture.[6]
A popular misconception is that UFO sightings by the masses increased precipitously after a widely publicized incident reported by businessman pilot Kenneth Arnold in 1947 (a sighting that also gave rise to the popular terms "flying saucer" and "flying disc"). However mass public reports, or "UFO waves", were also recorded in the U.S. in 1886, 1897, 1908-1916, 1909, 1913 and 1946[7]. While some studies have established that most UFO sightings are misidentifications of mundane objects — most commonly aircraft, balloons, or astronomical objects such as meteors or bright planets — and a percentage of reported UFOs are the result of hoaxes [8] in the largest study of its kind ever conducted, the Battelle Institute's Project Blue Book Special Report No. 14 (1955), concluded that more than 21% of the nearly 3000 reports it analysed remained designated as "unknown" [9] - that is, unable to be explained in mundane terms.
Nevertheless the mere possibility that all UFO sightings are misidentifications of known natural phenomena[10] coupled with a general perception of a paucity of empirical data, has inspired some debate in the scientific community about whether scientific investigation was or is warranted .[11][12][13][14][15] Very little peer-reviewed literature has been published in which scientists have proposed, studied or supported non-prosaic explanations for UFOs.[16] Nevertheless, UFOs as a cultural phenomenon continues to be the subject of serious academic research[16] and amateur investigators continue to advocate that UFOs represent real but unexplained events.
