Are you saying this physical universe is ruled or guided by direct intelligent design?
No of course not. I am saying the exact opposite. If the god of christianity existed the world would look very different.
I think the physical universe is ruled by impersonal natural laws. Only these natural laws were designed metaphysically outside the physical universe.
According to christians these natural laws were designed by god.
And these natural laws probably are necessary for the best world to harbor free-willed agents.
A world where tectonic plates didn't get stuck for hundreds of years and then kill hundreds of thousands as they release would be a better one. Free-will has nothing to do with it. If you affirm that god acts in the world you have no way out of this dilemma. If you don't affirm that god acts in the world then you are not a christian.
