You: What are these things that can only be explained by God's action?

Aaron: I do not know any more than you know, although I believe that some, such as the afore-mentioned "random" actions of atoms, are good contenders. It is the job of scientists to discover that are the inexplicable phenomena, and I do not claim that their work is yet done.

You: If it is not known that actions can only be explained by divine intervention, then the only being that knows what they are is God. There is no test for finding out what God knows and there is no test that will reveal to us whether an explanation for a phenomena will be found in the future. Because of this, people could go on investigating the cause of certain inexplicable acts forever and never discover whether God is causing them or the answer is just eluding them.

Because of these problems, there is no way to determine if there are any forces of nature that can be explained only by God. You are giving scientists an impossible task to perform. In addition, because we cannot prove that there is even one action that must be attributed to God, we cannot infer the existence of God from any actions.

Aaron: That is quite a compelling argument, and I will have to give it some consideration. In the mean time, let me tell you of another.
