How did people react to electricity?

People were amazed to see this miraculous form of light in which there was no gas, no flame, no oil, just a visible stream of energy. At first they didn't understand how it worked because you can't see the electricity. So, it was viewed as something magical by most of the people.

How were they supposed to react to it. Electricity wasn't discovered because it always existed. We always have known about the existence of electricity since the stone age with electric eels and comes it comes from the freaking sky. This question is like asking how did people react to rain. See? It doesn't make sense because it always happened before anyone started utilizing it.
