What I find interesting about irrational versus rational explanations for things is that people like me, who want to find a rational explanation for odd-seeming phenomena, are usually perfectly open to there being more than one.
e.g.:
Someone came into your church in a wheelchair and got up and danced in the middle of the service after the Holy Spirit was invited to come down on them? Well, OK, it happened, so they were (a) not really disabled (b) a stooge/plant (c) someone with a condition like M.E. which has good and bad days (d) quite able to dance, but in a bit of pain... etc. It could be any of them.
e.g.:
Odd smudge on the photo? Hmmm, well, that might be (a) light reflection (b) a lens scratch (c) an oddity caused in development (d) a thumbprint....
And so on. We don't argue angrily for it being one to the exclusion of all others.
Whereas people who want to find a supernatural explanation - despite the fact that there are, if you believe that sort of thing, literally thousands on offer - always seem to want their particular favourite one to be the only answer. It was God! It was angels! It was demons! It was a ghost! It was crystal healing! And so on.
Confirmation bias, pure and simple. If you believe in Woo A, you will be looking for examples of Woo A at work in the world and attribute things to it. If you believe in Woo B, you will be looking for examples of Woo B at work in the world and attribute things to it. And so on.
