Hey, I started this thread on a lark. Great that it lumbers on.
Some of the explanations for electricity make it more difficult to understand.
I will back off and say this now: I know that something powers my laptop computer and my smartphone. I don't have to understand it to believe the power exists. Whether I get that electrons don't flow like water or that it's a fair analogy to describe the results to a layperson, it doesn't matter.
Some have to be told this in order to apply it to other things.
Even as I write this, knowing that leaving off the obvious conclusion will cause people to go both ways: YES, WHAT I BELIEVE IN IS OBVIOUS AND HAS PLENTY OF EVIDENCE. EVOLUTION IS TRUE, EVOLUTION IS FALSE. THE GOD OF CHRISTIANITY EXISTS, THE GOD OF CHRISTIANITY DOESN'T EXIST. ETC. ETC.
