The oldest Moon rock is not old enough. Scientists largely agree about the history of the Moon's formation. However, they have not been able to date it exactly, as none of the Moon rocks brought to Earth by the astronauts of the six Apollo missions and the three Soviet Luna robotic missions directly record the age of Earth's natural satellite.
