The [supernatural] answer does not in any way increase your understanding about how thunder and lightning actually work. All it does is stp you from being curious.
Even more, at no time in human history have we verified that the supernatural is the cause of anything. Not only does it stop you from being curious, it also has the side effect of making you wrong when there is the discovery of a verifiable cause for an observed phenomenon.
I also do not know of a single "mysterious answer" that has any pragmatic use. You shouldn't stand in the middle of an open field holding a 10 foot metal antenna while standing in a pool of salt water whether or not Thor makes lightning.
