Earth (Mirror UnAnything fork)
From UnAnything Wiki
Earth is a planet in the Solar System with a lot of water and trumpets. Humans who lived on this planet in ancient times figured out it is round, but some humans who live there in modern times think it is flat.
Today, humans are the dominant species, but aliens think it is cars and that they can talk to them. Some people think dinosaurs used to be the dominant species, but others think it was always humans.
