This question has been on my mind lately. Primus made all of the Transformers, and just like our religious gods, his origin is very undefined, sketchy, and enigmatic. If Primus made Cybertron, the Transformers, and everything related to them, who made him? Was he made by some alien race we don't know about? Did he just form on his own through some strange process? Was he a member of a long dead race of the robots similar to the Transformers that evolved into a God? If anyone can shed light on this, or tell me their theories, I would appreciate it very much.
