First contact (science fiction)


First contact is a common science fiction theme 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.
The theme allows authors to explore such topics such as xenophobia, transcendentalism, and basic linguistics by adapting the anthropological topic of first contact to extraterrestrial cultures.

Overview

's 1945 novelette "First Contact" established the term "first contact" in science fiction, although the theme had appeared earlier. Its roots lie in colonial narratives from the Age of Discovery onward.
Of many variations of the trope, one may recognize the subclasses of the actual interstellar meeting of two civilizations and the "message from space" one.
