⭐ Core Definition: First contact (science fiction)

First contact is a common theme in science fiction about the first meeting between humans and extraterrestrial life, or of any sentient species' first encounter with another one, given they are from different planets or natural satellites. It is closely related to the anthropological idea of first contact.

Popularized by the 1897 book The War of the Worlds by H. G. Wells, the concept was commonly used throughout the 1950s and 60s, often as an allegory for Soviet infiltration and invasion. The 1960s American television series Star Trek introduced the concept of the "Prime Directive", a regulation intended to limit the negative consequences of first contact.

👉 First contact (science fiction) in the context of Alien invasion

Alien invasion or space invasion is a common feature in science fiction stories and films, in which extraterrestrial lifeforms invade Earth to exterminate and supplant human life, enslave it, harvest people for food, steal the planet's resources, or destroy the planet altogether. It can be considered as a science-fiction subgenre of the invasion literature, expanded by H. G. Wells's seminal alien invasion novel The War of the Worlds, and is a type of 'first contact' science fiction.

Experts consider the prospects of an actual invasion of Earth by extraterrestrials to be extremely unlikely, due to the enormous cost in time and resources.
