Our solar system bears witness to orderly, careful design. Consider the slant of our earth, tilted at a 23° angle. If it wasn't so tilted, we would lose not only our seasons, but life itself, as the vapors from the ocean would move north and south, piling up continents of ice.

Or the distance to the moon. If our moon were closer, our tides would daily inundate whole continents.

Or the circular orbits of our planets around the sun, all on the same plane. In the past half-dozen years some twenty planets have been discovered outside our solar system, and half of them move in egg-shaped "killer orbits" that lead to potential cosmic collisions.
