Earth (地球, Chikyuu) is the planet where the main narrative of Evangelion occurs.
The First Ancestral Race selected Earth as the home planet for the Seed of Life that would later be called Adam. Unfortunately, due to unforeseen circumstances, another Seed of Life, Lilith landed on Earth in an incident called Giant Impact, which also lead directly to the formation of Earth's Moon.
Following Giant Impact, Adam was placed in suspended animation by its companion Spear of Longinus and Lilith's progeny would come to be the dominant form of life on the planet.
However, Adam remained alive and her progeny remained viable for billions of years.
