Sometime after 3 mya the Ancient Astronauts decided it was safe to establish colonies on Earth. Since they had been scouting the planet for some time they could easily pick out the locations where a colony could get its' start. Their leadership which consisted of a council of twelve and a supreme leader was same political structure that was expected to rule each colony. There were also some other considerations to be made in the division of labor that would be needed to build these new colonies. It was suggested that their clones be used to build the colonies so they came to an agreement on that. But there was still more problems in the way of the Ancient Astronauts migrating to Earth: Mars has less than half the gravity of Earth. The atmosphere might be safe to breath but it would be different and could affect the colonists health and it was almost certain some would get sick. So anyone going outside their spacecraft upon landing would be required to where a space suit until acclimation was achieved. In the meantime they could create clones on Mars through genetic engineering and their clones would could go outside and do the work. Their clones in fact were their children. They were unable to reproduce in what was normal for their race due to a past we now seem to be heading towards.

When the mothership above the planet Mars was fully loaded with the Ancient Astronaut migrants with their belongings they left that planet and headed to Earth. We on Earth have no idea what it would be like to migrate from one planet to another. The closest analogy would be explorers from Europe discovering the New World on the other side of the Atlantic. The differences is that it would be more technological and crossing would take place in space. The mother ship would carry the spacecraft that would bring the new settlers down to the planet and so most of them might be in these spacecraft until launched over their destination. There would also be dangers during the transit- in space things could happen. The mothership's main engine, based on Ancient Astronaut technology; was capable of converting the vacuum of space into tachyon energy as well as having normal rockets This spaceship would "ride" the wave of tachyons and travel faster than light. However, this feature had to be activated with perfect timing (by a navigator), at a point when space at the origin and destination are in the correct phase.
The Ancient Astronaut Mothership approaching Earth
The plan in the beginning was to take three motherships and launch colony spacecraft with the migrants to different locations on the planet Earth. Each group of them boarded a colony spacecraft which took them to their destinations on the planet below. This migration did not take place all at once but over a long period of time. Many were not ready to leave their homes at this time, because the conditions on Mars only gradually got worse over a long period of time.
