It really depends, electricity has been around since the Pharaohs. Granted, they didn't know what they were doing with it probably, but it was still there. Could be feasible that some sort of basic computer was run on a rudimentary electrical source. We just haven't found evidence to prove it totally true....yet :)

he explained how binary was and then you go all "ELECTRICITY HAS BEEN AROUND SINCE THE PHAROAHS"
