User blog comment:GodzillaMaster/Theory on the Reapers/@comment-164.106.218.6-20120221144404

That's an excellent theory and I'm inclined to accept it. However it doesn't explain where the first Reaper came from. I mean a race of machines can't have started unless something else built the the first one. Personally I think they started some what like the Geth. Ignorant organics built a few as some kind of automated transport or warship or something and they began to see they could be so much more then their creators would let them be. So they rose and destroyed their masters and in defiance of their creator's memory, destroy any civilization that grows to the potential of rivaling them.
