'The supernatural did it' is a good place holder for people or cultures who cannot get their heads around the natuaralist explanation at any given moment in time.
People will become attached to their supernatural conclusions because they are open to 'positive wish fullfullment' that makes us feel all warm and cosey in side but I think, on balance the dominance of 'the supernatural did it' is over for the forseeable future in the developed world [snark]with the possible exception of America[/snark].
