  If there is no explanation for why the spheres behave in this fashion, or why some stars and planets emit more light than others, or why some regions of the heavens are relatively crowded while others are empty, there is no reason to think the phenomena in question are what they are by virtue of necessity. If there is no necessity, there are no grounds for eternity. The alternative is to say that God created the world as a result of a free choice and fashioned it in a particular way.
