And God should be played by Billy Crystal. Dunno why but it just poped in my head and it's amused me ever since.
I was thinking that too, with the premise behind Caprica, it seems like they were trying the same thing with humans. Which begs the question, how are Cylons different than humans? Anders sure seemed to have a human brain. And yes you never see wires. Eights can plug into electronics but you don't see the Final Five doing it. I'm thinking maybe they were genetically engineered to be servants as opposed to machine-built, with enhancements but couldn't reproduce. Of course they didn't like it, war, yada yada, but they left humans on decent terms and went the other way.
