Problem
The universe is like a house, in that every part appears to be carefully and skillfully designed for some purpose. In a house, for instance, the steps of the stairs are designed at exactly the right height and size for humans to walk up them. Likewise, we find in nature all kinds of things that are perfectly suited for some creature or other to use in some way. But you will notice that whenever we see a house, we can be confident that it has some creator. Likewise, we should infer that the universe as a whole has some creator.
