Earth is a planet that appears in Xenoblade Chronicles X. Its earliest life arose at least 3.5 billion years ago, with the planet being 4.54 billion years old. It was the home of Humans, and by 2054, Earth had a population of 10 billion Humans. In July 2054, two alien races fought a massive battle over Earth. Unfortunately, the planet was left devastated from the battle, leaving humanity to seek out new worlds in massive Ark Ships. However, most of these Ark Ships were shot down while trying to escape Earth's gravitational field, and only a few made it out. The planet was eventually destroyed in a massive explosion.
