Life comes from the sun. The sun gives us energy! Just like... okay, think of if you bury something dead as fertilizer, like those bags of fish parts they sell. That's fuelling life, but even with that, nothing would grow without the sun. We all need the sun -- if it ever went out, the world would go cold and die quickly. And for Kryptonians, our bodies react differently to other suns. That's why the sun is so important. It's why we talk about light and brightness all the time.

...or, uh. Why I do, I guess there isn't anybody else here to do it, huh.
