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 writers to explore such topics such as xenophobia, transcendentalism, and basic linguistics by adapting the anthropological topic of first contact to extraterrestrial cultures.
