The statement is false.
Earth is not a ''spaceship'', and that term is used only metaphorically in some studies about the future of the human kind, in the sense of ''can the Earth be used as a spaceship to bring us to another place'', and theorize about that. In the scientific circles, this term is not used for describing planets, including the Earth.
