S0E6: The Ultimate Evidence: Alien Power Plants

Did our ancestors have an understanding of how to generate power thousands of years before modern man?

But if our ancestors did possess power, where did they gain this knowledge? Is it possible that they received this wisdom from an extraterrestrial source as ancient astronaut theorists contend? And, if so, why did the power stop flowing?
