Earth

This is the homeworld of ALL mankind, no matter what the Nazis think! It is roughly 5 billion years old and is currently inhabited by 7 billion homo sapiens of varying intelligence, opinions, ethnicity, religious background, and race. There are roughly 1 million Nazis currently living in secret on the dark side of the Moon, where they have lived for 68 years after fleeing Earth's surface by way of a base in Antarctica. On the Moon, the Lunar Nazis have constructed massive bases and ships, including their Black Sun and the Almighty Gotterdammerung space superdreadnought.
