Well, do you want to live in a world that doesn't have just a little bit of magic in it?

Because in a strictly empirical world, there is no sun, just a ball of flaming gas, and iy doesn't rise, it comes into view as the planet rotates. In that world, there is no Christmas. There is nothing but the efficient business of survival and reproduction.

But if you add that little bit of imagination (which is all that magic is), then the sun rises to begin a new day. A day in which to live, love and enjoy. That world has Christmas in it.
