Aliens
Childhood's End is a 1953 science fiction novel by the British author Arthur C. Clarke, in which aliens come to Earth, human children develop fantastic powers and the planet is destroyed.
Argentine comic writer Héctor Germán Oesterheld's comic series El Eternauta (1957 to 1959), an alien race only mentioned by the protagonists as Ellos ("Them") invades the Earth starting with a deadly snowfall and then using other alien races to defeat the remaining humans.
Douglas Adams's Hitchhiker's Guide series (1979–2009)^[24] is a humorous take on alien invasion stories. Multiple Earths are repeatedly "demolished" by the bureaucratic Vogons to make way for a hyperspace bypass, to the chagrin of the protagonist Arthur Dent.
In Gene Wolfe's The Urth of the New Sun (1987), aliens (or highly evolved humans) introduce a white hole into the sun to counteract the dimming effect of a black hole, and the resulting global warming causes a sea-level rise that kills most of the population (though this may be redemptive, like Noah's Flood, rather than a disaster).
In Greg Bear's The Forge of God (1987), Earth is destroyed in an alien attack. Just prior to this, a different group of aliens is able to save samples of the biosphere and a small number of people, resettling them on Mars. Some of these form the crew of a ship to hunt down the homeworld of the killers, as described in the sequel, Anvil of Stars (1992).
Al Sarrantonio's Moonbane (1989) concerns the origin of werewolves (which he attributes to the Moon, which is why they are so attracted to it), and an invasion after an explosion on Luna sends meteoric fragments containing latent lycanthropes to Earth, who thrive in our planet's oxygen-rich atmosphere. Moonbane's tone is reminiscent of H. G. Wells' War of the Worlds (1897).
Charles R. Pellegrino and George Zebrowski's novel The Killing Star (1995) describes a devastating attack on a late-21st-century Earth by an alien civilization. Using relativistic missiles, they are determined to destroy the human race in a preemptive strike, as they are considered, after watching several episodes of Star Trek: The Next Generation which shows human domination in space, a future threat.
The World's End is a 2013 British-American comic science fiction film directed by Edgar Wright, written by Wright and Simon Pegg, and starring Pegg, Nick Frost, Paddy Considine, Martin Freeman, Eddie Marsan and Rosamund Pike. The film follows a group of friends who discover an alien invasion during a pub crawl in their hometown.
In the 2018 horror film A Quiet Place and the 2021 sequel A Quiet Place Part II, society has collapsed in the wake of lethal attacks by (apparently) extraterrestrial creatures who, having no eyesight, hunt humans and other creatures with their highly sensitive hearing; the scattered survivors live most of their lives in near-silence as a result.
