The Terrabots came into existence during the Sun's formation, around 4,600,000,000 BC. They later created the Earth with various small asteroids merged together to form the planet we now call Earth. Earth was in a very unstable state when it was created. Knowing this, the Lunabots, another robot humanoid race, created the Moon in 4,500,000,000 BC. In 4,000,000,000 BC, the Terrabots turned the Earth from having a hot and molten surface, to being very much like it is today.
