Why is blue blue?

Emily, who is currently 6, is very inquisitive about the world. Like many kids her age, she asks many, many questions of her parents. Some of them are funny, some are cute, some are difficult to answer. She recently asked one that was particularly tricky – in her words: “Why does green have to be green and blue have to be blue?”

Well. How do you even start to answer that so a 6-year-old will understand it? How do you talk about the visible spectrum of light and wavelengths? How do you approach the idea that what you see as blue or green may not be what someone else sees – she’s too young to watch The Matrix, after all. I’m not even sure I know the answer. Needless to say, when we tried to answer her she looked at us, uncomprehending, and the longer we talked, the more her look became glazed.

When it had become inescapable that we were failing to answer her question, I asked her if we’d just confused her. She nodded. I then asked her what she thought the answer was. “God decided.” Of course. I might have known. Emily and her big sister Katie are still at that age where ‘god did it’ is an easy go-to answer for something they don’t yet understand.

They’re not alone – as a species we’ve been doing it for thousands of years. It’s a part of us I don’t think we’ll ever truly lose, no matter how much horseshit I consider it to be. I think that’s the case because we’ll never know everything – some things I think will always be a mystery to us. And as long as there’s something we don’t know, there will be something for folks to point at and say ‘god did it’ as if the very fact that we don’t yet know something is somehow proof of god’s existence. Even though, to quote the excellent Tim Minchin, “Every mystery ever solved has turned out to be not magic.” Every riddle we unravel reveals two more behind it.

This is the way religion has insinuated its way into the lives of men, women and children for generations; it seems like an easy answer for people who want to know how the world works. The way to overcome it is to learn more, to know more. This is why I always try to answer my kids’ questions, and never discourage them from asking them, even though sometimes you really want them to just shut the hell up and give you 5 minutes to think; even though I have the tiniest bit of sympathy for the parent referred to in Neko Case’s Nearly Midnight, Honolulu. Katie is already questioning the logistics of Father Christmas making it all the way around the world in one night, and I don’t think the stock answer of ‘it’s Christmas magic’ will work for much longer. This unquenchable curiosity will, I hope, one day dislodge from their mind this acceptance that ‘god decided’ everything they don’t understand and they start looking for a better answer.

Neko Case: Nearly Midnight, Honolulu: “You’ll hear yourself complain, but don’t you ever shut up please kid have your say.”
