Does all of God's creation have a purpose?

The notion that everything must have a purpose is simply ridiculous - at least in any deistic way. Celestial objects including stars, planets, black holes, supernovae, cosmic rays, gravity, and dark energy (among other things) all influence each other and affect the cosmos in certain ways, and in this sense alone, have a purpose. God (which may or may not exist) has nothing to do with it.

There are objects in space which are far away which have contributed to the creation of Earth and the development of the human race. Huge planets in the outer parts of the Solar System have diverted and destroyed things which could have destroyed the Earth while massive climate changes have forced evolutionary changes on life. According to the OT Gawd killed 2.2 million while Satan did in only 10 people. Did Mercury have an productive part in Earth's history? Maybe? Then again we are made from the ashes of stellar explosion which converted hydrogen into other elements. The collapse of stars involves the creation of large quantities of carbon. Someday will we visit a mass floating past Earth and discover a diamond a few miles across?

Interesting Donald Dumpsfiels. But is this relevant to this poll?

Well thank you for your replies, guys.
I agree that there are certain celestial objects which are important to the Earth, not including the obvious one of the Sun, and, to a lesser extent, the Moon. For instance, the planet Jupiter is in a position where it can sometimes attract incoming comets, which might otherwise have collided with Earth! This is one idea.
However, the planet Mercury appears irrelevant. It is very small, not too much bigger than our Moon. It is, to me, just a small piece of celestial junk. I simply have to ask myself, why would God create a planet like that? It could disappear tonight, and there would not be the slightest effect on the Earth. If God is the creator, why did He create it? Even Christians are stuck on that one.
I guess one religious answer could be that God created the Universe good, but Satan brought ruin upon it.

This is a wierd semantic point and sort of a pagan view. I believe that celestial bodies are alive in a sense. The earth produces life and the sun has influence on it. It seems to defy logic that dead things produce life. Therefore the earth and sun as goddess and god archetypes make much more sense to me than the idea of a jealous old bearded white guy that created the universe in less than a week with a book written by humans explaining the whole process verbatum. People with my viewpoint have been burned as witches throughout history, yet most Americans believe the latter view. Your question is interesting and worth exploring regardless of someones spiritual/religious views.
