Do aliens exist? Hundreds of pictures and videos of UFOs are taken every year and enthusiasts believe many of them could be proof or even a hidden conspiracy. While some have been debunked as fake, there are still dozens that have left even the experts scratching their heads and wondering if we really have been visited by creatures from another planet.
Unidentified flying objects (UFOs) are things seen in the sky that cannot be identified or explained. UFOs are often associated with aliens and conspiracy theories. @AlienPlanet#
An unidentified flying object, or UFO, is in its strictest definition any apparent object in the sky that is not identifiable as a known object or phenomenon. However the term is widely used in popular culture to refer more specifically to supposed observations of craft of extraterrestrial origin.
Most UFOs are later identified as conventional objects or phenomena (e.g., aircraft, weather balloons, clouds). Some of them are not identified, either because of lack of evidence or because no conventional explanation can be found despite extensive evidence. Some people consider the latter cases as possible observations of extraterrestrial space craft. @AlienPlanet#
