Earth

Earth is the planet you're most likely on right now. It's the third planet from the Sun in our solar system and is the only known planet in the universe to harbor — not support — life. It's 4.5 billion years old, just a few ten million years younger than the solar system it's in. Earth is orbited by a singular natural satellite with the most creative name of any entity in the entire universe: the Moon. Yeah.



In fiction, Earth is the planet that the story most likely occurs on. In both fiction and real life, humans live here on this ball of rock and water. Since it's usually the only planet that humans live on, whenever someone tries to kill it because lol, someone else must step forth and stop them. In the science fiction genre, aliens seem to either hate Earth and want to destroy it or conquer it and enslave its weak, fleshy inhabitants.
