As I said the greatness of the universe doesn't prove it's designed. Also your analogy is wrong because machines have a purpose or a job, what is the universe job or purpose? If it is to contain life, for example, then it does a poor job considering most of it it's inhabitable even a big part of earth.
Well, actually, here is where you are wrong.
It is stating that the universe is great that doesn't prove its design. Why not? Because stating such doesn't show anything at all. Stating such is simply political science.
Showing the greatness through examination of it proves the design.
Some of the purpose of God in creating the universe, was to express His love for mankind. He had other purposes in mind, as well. So there is purpose for the machine. How do we know? The universe is a machine full of machines, and every machine is designed for some purpose.
Habitation of the earth isn't the problem. People working together is the problem. After all, look at the inhabitants of harsh Antarctica who work together, just so that they can inhabit it.
