Overview

An Alien by definition is any object or being that is in another place to where it was created or born. Often the term Alien is applied to any race of beings from another planet arriving on earth or a planet colonized by Human-beings (even the local inhabitants of that planet maybe referred to as aliens by the humans even though strictly by definition the human are the aliens).

Aliens may be benign or aggressive and are a popular protagonist in modern science fiction and culture in general.

Alien can also refer to the other-worldly i.e. things that do not resemble the normal and recognizable.
