This rundown by "InActionMan" on aintitcoolnews is the best summary I've seen. I've clipped some commentary out of it a bit.
-The knowledge of the creation of humans/Cylons is not completely known to the final 5 (6?) Cylons. They do know that:
- The thirteenth tribe of all Cylons left Kobol thousands of years ago for a planet they called "Earth".
The twelve tribes of humans left Kobol thousands of years ago for the colonies.
-The humanoid Cylons on Earth gave up resurrection for procreation.
-The humanoid Cylons on Earth created mechanical Cylons to be slaves to do the dirty jobs they did not want to do. The mechanical earth colons rebelled and apparently destroyed themselves and the humanoid Cylons on "Earth"
-The five humanoid Cylons on "Earth" rediscovered resurrection technology and used it to survive the holocaust on "Earth".
-The “Final Five” then traveled to the colonies without FTL technology to try to warn the 12 colonies not to build robots and repeat the cycle. Which took the “Final Five” thousands of years.
This is the part that probably went over the heads of most of the general audience. Less of a problem for us geeks, but Moore and company really should know that most people do not have even a basic understanding of general relativity. For a guy who keeps saying that he is trying to make a science fiction show that is accessible for the general public that is a major blunder.
For anyone that does not know about Einstein’s Theory of Relativity here is my best layman’s explanation:
One of the things Einstein says is that time is not a constant. Time is in fact "relative" or changeable and can be warped or adjusted by mass. When a spaceship starts to move faster and faster toward the speed of light it becomes more massive (i.e. heavy) this causes time to slow down. This slow down of time is not perceptible to the person on the space ship but, from the perspective of someone standing on a planet the spaceship person would seem to be moving very slowly. So it took the “Final Five” thousands of years from our perspective or the perspective of someone on a planet to travel from "Earth to the colonies. From the perspective of the five because time moved slower for them in their spaceship and it took years but not thousands of years to reach the colonies.
The “Final Five” arrived at the colonies too late to stop the colonist from creating robot Cylons and the war was already under way. The “Final Five” convinced the mechanical colony Cylons to stop the war in exchange for giving them “skinjob” technology and resurrection. The “Final Five” however did not teach the colony Cylons how resurrection actually worked. Ellen also apparently placed an “Easter Egg” about the “Final Five” into the resurrection process.
John/Cavil became angry because he felt that his humanoid body was limiting and because he was jealous that he was not Ellen’s favorite. Cavil killed the Sevens/Daniels. Killed the “Final Five” and allowed them to resurrect into new bodies with their memories wiped and deposited them in the colonies one by one over the last forty years. He wiped any knowledge of the “Final Five” from the memories of the 2s, 3s, 4s, 5s, 6s and 8s.
<snip some commentary unrelated to the rundown>
Finally apparently the colony mechanical Cylons came up with the idea of monotheism and the true nature of God and his hand in events has yet to be revealed.
