- "How blithely you use the word alien; you have no idea how alien a thing can be."
- ― The Dark Side of the Sun, Terry Pratchett
- "This planet is the home to the largest mass of organic creatures ever seen. What breeds down in the pits of the planet is unknown and unrecognizable, but can be purchased for a low price at Woboo: Land O' Meat."

- "Oh my god, how are you doing that?"
"I'm from outerspace, Jeff. I can do lots of cool shit."

- "No one would have believed in the early years of the 21st century that this world was being watched by intelligences greater than our own, that as men and women busied themselves about their various concerns, they observed and studied, perhaps almost as narrowly as we, with a microscope might observe the transient creatures that swarm and multiply in a drop of water. With infinite complacency, humanity went to and fro about the globe, serene in their assurance of their empire over matter. No one gave a thought of the other worlds of space as sources of human danger or thought of them only to dismiss the idea of life upon them as impossible or improbable. Yet, across the gulf of space, minds that are to our minds as ours to those of the beasts that perish, intellects vast and cool and unsympathetic regarded our planet with envious eyes and slowly, and surely, drew their plans against us."
