Actually, a good alternative to the question would be "What historic event fills you with the most amount of 'I Don't Know'?"runic knight said:I get the question but still find it worded poorly.
Basically, what event in history is most likely only explainable by supernatural force.
the problem with this question is that skeptics and usually atheists represent a way of thinking. That way of thinking involves not making a decision without proper evidence. The very answer of "I don't know" is valid, excepted and outright expected from a true skeptic when asked about something they do not have proper evidence on in order to make a judgement.
So what you have done is asked someone who wont give an answer just to fill in the blanks which question they would most likely just fill in the blanks of just to have it answered.
When talking about a supernatural solution to a skeptic, what you are doing is literally asking them to forgo the honest "I do not know" and instead give an answer they know to be contrary to their fundamental philosophies just to fill in the blank.
So, what question exists that I would rather lie to myself to answer then honestly just say "I do not know"? Well, I don't know what question I would do that about. I suppose I might throw out the "why do bad things happen to good people" or some such crap just for the sake of an answer there. Blaming a dick of a god for the evils in the world is partially tolerable if I am forbidden to otherwise answer "I don't know" or give an answer based in personal thoughts rather then evidence.
The "insert supernatural here" aspect is just a hook, a hook that seems to be breaking a lot of peoples' brains (to hilarious results). The question is best answered specifically with a situation that makes you shrug.
For instance, in my first post, I suggested the park ranger who was struck by lightning seven times. Sure, there's always the explanation of "positively tragic luck" or the dude just flagrantly disregarding all safety rules, but it's unlikely to the point that I could see an irritated god trying to get his attention by hurling lightning bolts.
It's not hard, and it's not a compromising of your ethical/logical fibre to imagine bizarre circumstances and the idea that a god could have enforced them.
I mean, you play games, right? Those are positively brimming with scientific failures and supernatural WTFery...
