Re: whoever built the pyramids had knowledge of electrical power
I would find this more convincing if we had ever found the trappings of large scale power generation and distribution in Egypt. We havent to my recollection. There is a clear progression of learning if you look at the archeological evidence. Their first few pyramids were utter failures. Did the aliens fail to take basic civil engineering in alien college or something?
If you are not part of the solution, you are part of the precipitate.
