Etymology

The term "UFO" is an acronym coined in the mid-20th century during the rise of modern aviation and space exploration. It reflects a straightforward descriptive approach:

  • "Unidentified" highlights the lack of clear explanation.
  • "Flying" specifies the object's movement or location.
  • "Object" generalizes the phenomenon as a tangible (or perceived) entity.
    Originally a neutral military term, it later became culturally associated with extraterrestrial theories due to popular media and unexplained sightings.
