Quotes: Alien Invasion

"Think about this. According to the movies, out there in space, untold light years from Earth, exist many alien species with the ability to travel between the stars and send messages across the universe. Their civilizations must be wonderfully advanced, and yet, when we finally encounter them, what do we get? Disgusting, slimy morph-creatures with rows of evil teeth, whose greatest cultural achievement is jumping out at people from behind things. How do they travel through space? By jumping out from behind one star after another?"

"There's an evil alien race that's about two parts Combine, to two parts Covenant, to one part Snatcher (now there's an obscure reference; I'll probably bring up Flight Of The Amazon Queen next), and they want to invade the Earth because they always do. What the fuck's so great about Earth? Good school district, handy for the shops, what?"

Once, I saw xenos as a terrifying threat, the harbingers of our galaxy's destruction. Now I know them for what thery are. Vermins, parasites, suckling at the wounds of a galaxy that already belongs to mankind.

Little Audrey, "Dizzy Dishes", (1955)

Stavrou: No. From Canada.

In our obsession with antagonisms of the moment, we often forget how much unites all the members of humanity. Perhaps we need some outside, universal threat to make us recognize this common bond. I occasionally think how quickly our differences worldwide would vanish if we were facing an alien threat from outside this world.
Ronald Reagan note 

"No one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's. [...] Yet across the gulf of space, minds that are to our minds as ours are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded this earth with envious eyes, and slowly and surely drew their plans against us."
