Studies have established that the majority of UFO observations are misidentified conventional objects or natural phenomena-most commonly aircraft, balloons, noctilucent clouds, nacreous clouds, or astronomical objects such as meteors or bright planets with a small percentage even being hoaxes [REF].
While UFOs have been the subject of extensive investigation by various governments and although a few scientists have supported the extraterrestrial hypothesis, almost no scientific papers about UFOs have been published in peer-reviewed journals [REF].
