Okay, so we think or at least know the Fallen got here before the Allspark, eh? But what if Primus was the life source of Cybertron before the Allspark and he went searching for something. The Allspark was built as a subsitute for Primus. Then, when our Robot God reached Earth, his programming went glitchly and crashed on Earth, cooling the temperature on Earth. Eons later, the Fallen was exiled from Cbys and ventured to Cybertron. Soon, he had enough power to enslave the humans and everythin else. Then, Primus was awakened out of stasis lock and used his energy to trap the Fallen in the earth with him, while the humans built monuments to cover his existence. Before he went offline, Primus created a temple in Egypt that would awaken him in a time of true despair. When he does wake, this is what I hope it would look like on a movie scale.
