Fair comment. I think I like a bit of order and sense in my world (though you'd not believe it looking at my desk) and maybe that's a human thing isn't it. Wanting firm explanations and reasons and sense. But not everything is easy to make sense of, maybe lots of it won't ever make sense.

This is slightly off at a tangent, but I was reading this rather interesting account of an expedition in the arctic
http://www.biodiversitylibrary.org/item/100355#page/25/mode/1up
(a few pages back there's an excellent account of building an igloo)
but that page talks about them watching the aurora borealis. And they think they can hear it, but they're not sure. They're not sure it's their imaginations or whether it's real.

And so I thought I'd have a quick google about it and it seems it's still a contentious thing - maybe they DO make a noise, or maybe they do something that means some people can detect it and some maybe can't
