Alien invasion

An alien invasion is when aliens invade the Earth to exterminate and destroy life. It is a common feature in science fiction. Scientists consider the possibilities of an alien invasion in real life would be impossible. H. G. Wells' The War of the Worlds was very successful and is considered as the seminal alien invasion story.
