I actually believe that the Reapers were invented by the Keepers. But they were not the Keepers at the time. They were the first space-faring race, like evah. I say this because, it is a very classic and obvious approach to have the first intelligent species be giant bugs.

The Keepers constructed the Reapers and they turned on the Keepers. Obviously.

But wait. Why did the Keepers Build these godlike war machines? What were they planning to fight with the Reapers? What horrible whatever could only be battled with an army of near-indestructible AI warships? *MIND = BLOWN*
