So we have been filled on a few details regarding the Prime back story. We know Cybertron is uninhabitable and Autobots and Decepticons are scattered. Earth and other planets were used to deposit mass amounts of energon. We know Optimus stated there had been no Decepticon activity on Earth (for 3 years) as of Darkness Rising. But, it makes me wonder why the Autobots and Decepticons are on Earth in the first place and what happened. How did the Autobots forge the relationship with Fowler and obtain the Autobot Outpost Omega One. Why are there crashed ships on Earth. Why Cybertronian technology is just randomly on Earth, (Energon Harvester, polarity gauntlet, etc.) I've just been wondering about these things. Does anyone have any ideas or anything else to add?
