Aliens

Extraterrestrial life, also called alien life, is life that occurs outside of Earth and that did not originate from Earth. These hypothetical life forms may range from simple prokaryotes to beings with civilizations far more advanced than humanity. The Drake equation speculates about the existence of intelligent life elsewhere in the universe. The science of extraterrestrial life in all its forms is known as exobiology.

Since the mid-20th century, there has been an ongoing search for signs of extraterrestrial life. This encompasses a search for current and historic extraterrestrial life, and a narrower search for extraterrestrial intelligent life. Depending on the category of search, methods range from the analysis of telescope and specimen data[3] to radios used to detect and send communication signals.

The concept of extraterrestrial life, and particularly extraterrestrial intelligence, has had a major cultural impact, chiefly in works of science fiction. Over the years, science fiction communicated scientific ideas, imagined a wide range of possibilities, and influenced public interest in and perspectives of extraterrestrial life. One shared space is the debate over the wisdom of attempting communication with extraterrestrial intelligence. Some encourage aggressive methods to try for contact with intelligent extraterrestrial life. Others—citing the tendency of technologically advanced human societies to enslave or wipe out less advanced societies—argue that it may be dangerous to actively call attention to Earth.

List of alleged extraterrestrial beings

FLATWOODS MONSTER

In West Virginia folklore, the Flatwoods monster, also known as the Braxton County Monster or Phantom of Flatwoods, is an entity reported to have been sighted in the town of Flatwoods in Braxton County, West Virginia, United States, on September 12, 1952, following the appearance of a bright object crossing the night sky. Nearly fifty years later, investigators concluded that the light was a meteor and the creature was a barn owl perched in a tree, with shadows making it appear to be a large humanoid.

GRAYS

are purported extraterrestrial beings whose existence is discussed in ufological, paranormal, and New Age communities and who are named for their unique skin color. Forty-three percent of all reported alien encounters in the United States describe Grey aliens. Such claims vary in every respect, including the nature, origins, moral dispositions, intentions, and physical appearances of the encountered beings, though many of them nonetheless share some noticeable similarities. A composite description derived from this overlap would have Greys as small-bodied beings with smooth grey-colored skin, enlarged hairless heads and large black eyes.

HOPKINGSVILLE GOBLIN

The Kelly–Hopkinsville encounter was a claimed close encounter with extraterrestrial beings in 1955 near Kelly and Hopkinsville in Christian County, Kentucky, United States. UFOlogists regard it as one of the most significant and well-documented cases in the history of UFO incidents, while skeptics say the reports were due to “the effects of excitement” and misidentification of natural phenomena such as meteors and owls. Psychologists have used the alleged incident as an academic example of pseudoscience to help students distinguish truth from fiction.
