Being very curious critters, us humans seem to have a need to have answers for everything. And, if the answer isn't there (because the cause or underlying phenomena has yet to be discovered), the majority of us (humans) hit the default magic explanation button - god, yahweh, allah, ganesha, quetzacoatl, etc. - made it happen.
In speaking with theists, I always get the impression that the 3 most feared words in the English language (regarding the unexplained) are, "I don't know." If the phenomena can be attributed to magic spirits, it gives them a sense of understanding (albeit false) and comfort.
I know it's an old adage, but an apropos one. Science has questions that may never be answered. Religion has answers that may never be questioned.
I don't jump to any conclusion, but assume that a logical explanation exists. I'll often check to see if similar events have occurred in the past. When the big blackout occurred in the northeast US about 7 years ago, a lot of people were freaking out thinking that it was a terrorist attack. I vaguely recalled hearing about some large blackouts in the 1970s, so I looked it up and confirmed that such blackouts had occurred before.
I am of the opinion that a supernatural explanation is, by definition, a lesser likely cause than a natural explanation.
I fall back on the scientific explanation: "Shit happens."
Really though, the expectation of some people that they have to have a quick answer to a question is the real problem here. The thing to learn though is when you don't have one, it's not necessary to make one up; at least, not if you're an adult.
