Typing and printing made possible by generations of people who had to be really confident in their control of electricity through transistors. You're taking a massive leap insofar as electromagnetic energy being a fundamental force of the universe having an unknown origin in the ultimate sense. It's the same way we have had hundreds of years of perfectly useful Newtonian gravity - going so far as to map the solar system with satellites, but can't make our model of the galaxy work without dark matter.

Also, we do see, hear, and feel lightning. And we can explain it. The intellectual dishonesty of "some people believe this or that" like these are worthwhile perspectives. It's sickening. Even given the perspective that we don't know, there's a certain lack of onus on one to use the scientific method to go figure it out. Like the purpose of science is to be told what is and what isn't correct.
