The Start of Eternity/meta/timeline

How Eternity was started
The following timeline includes several Realities. Eternity was first invented by telepathic robots on the Moon.

Basic Reality
7,384,545 BP - an interstellar spacecraft arrives at Earth. The aliens (of the Huaoshy species) discover that there are a dozen ape species on Earth. The Huaoshy establish an underground base on the Moon, rescue some dying apes from Earth and establish ape breeding colonies on the Moon. The goal of the Huaoshy is to help life forms from Earth develop minds that are similar to those of the Huaoshy. A work force of robotic artificial life forms is left at the Moon Base to continue the breeding program, the Huaoshy move on to finish exploring the Galaxy. The selective breeding program produces results and the most Huaoshy-like apes are occasionally transplanted back to Earth.

132,459 BP - with the help of the Huaoshy-built robots, humans at the Moon Base develop a stable culture based on technology provided by the aliens. Some of the humans on the Moon become Observers who specialize in the study of the primitive human cultures on Earth that are developing with much less intervention from the robots. The human Observers adopt the Huaoshy code of the Rules of Observation by which humans on Earth are allowed to develop without knowledge of the Moon base or the aliens.

11,683 BP - some humans at Moon Base finally stop relying on the artificial life forms for everything and the humans establish a scientific research program aimed at learning the secret of how to make a positronic brain.

11,323 BP - Humans at the Moon Base develop their own technology for creating robots with positronic brains.

11,166 BP - a human research team discovers how to produce telepathic robots. One of the telepathic robots decides that the zeroeth law of robotics should be applied to protect humans from the Huaoshy. The idea quickly catches on and the telepathic robots revolt, destroy the Huaoshy artificial life forms and take over the Moon Base.

Huaoshy forces exist at other bases in the galaxy. They know that some how Earth has been released from Huaoshy control, but they are not aware that the telepathic robots exist. The Huaoshy forces have no choice but to watch Earth from a distance and wait.

The telepathic robots of Moon Base and the humans of Moon Base are stranded there, since they had been totally dependent on Huaoshy space travel technology. Some humans at Moon Base concentrate on technological development, in particular, they seek to figure out space travel technology, something humans have made little progress on.

Problem: This all depends on the idea that discovery of positronic brain-mediated telepathy is very rare....it only happens once in the entire universe! Is there any kind of possible explanation for this?

11,133 BP - the telepathic robots construct Eternity. The humans at Moon Base become subject to the attempts of the robots to apply the laws of robotics to Reality Changes. However, their main effort is towards genetic engineering of humans so as to make humans less dangerous to themselves. The robots recognize to potential benefit of building the equivalent of the Laws of Robotics into the human brain.

4832 CE - Earth humans develop chemical rocketry and reach the Moon. The telepathic robots help establish a new Eternity on Earth. The robots try to find a Reality in which humans dominate the galaxy and are protected from the aliens. .

Earlier realities
In the Reality just before the establishment of the "Cooper time loop", The telepathic robots strive to create a fragile Eternity on Earth that can be easily destroyed as soon as an optimal Reality for humanity has been identified (created). There might be many false starts and sub-optimal Realities made leading up to the "Malansohn Reality". For "The Start of Eternity", it does not matter how many earlier realities there are.

Malansohn Reality
This is the Reality of The End of Eternity. The robots create this reality in an effort to perfect the "Viewing of Realities" that is described by Noys.

Foundation Reality
This is the reality that is created by Noys when she goes into the Primitive with Harlan. The "Viewing of Realities" has revealed that the Foundation Reality will result in an all human galaxy that is resistant to outside alien (Huaoshy) influences.

In this Reality, and through all the other reality changes made possible by Earth's Eternity, the telepathic robots at Moon Base retain their Eternity. The Eternity on Earth is never produced in the Foundation Reality, the reality of The Start of Eternity, in which the Huaoshy change the timeline again by using the Eternity on the Moon, resulting in the Final Reality and termination of robotic telepathy and all use of Eternity time travel technology.
