65 million years ago Maldek became the Asteroid Belt

 There was a nuclear war which broke the planet apart among the civilizations on Maldek of our ancestors. The remnants mostly of the politicians and Generals of the armies were the only ones mostly who survived from Maldek. Some went to Mars but Mars because of Asteroids from Maldek hitting there had purshed much of the atmosphere off of Mars then. Also around this time a piece of Maldek hit the Yucatan Peninsula on Earth and killed most of the larger dinosaurs so it was possible for Humanoids from Maldek to colonize the earth even though Earth has always been a Galactic National Park.
