What is an alien?
Alien derives, ultimately, from the Latin alienus and means that which belongs to something else. It is that which is foreign to the being experiencing it. It is strange. It need not be hostile, but could be. An alien, in this case an extra-terrestrial, is an organism that is not native to planet Earth. Once upon a time the common human pop cultural idea of the alien was a "little green man", possibly from Mars, but since the 1980s the most common form of alien believed to exist by the largest portion of the Earth population is the Grey type, often associated with Roswell, New Mexico. So pervasive is the Grey in human culture that analogs of it exist across popular media. Even Star Wars has its version, the Duros, purported to be one of the first, if not the actual first, space-faring species.
