A couple years ago I was presented with an argument against theism that appealed to the trustworthiness of the scientific method. It goes like this:
1. The scientific method relies on the constancy of the natural laws for its trustworthiness
2. In order for God to create, He must act in a way that breaks the constancy of the natural laws
3. Therefore, God creating and the trustworthiness of the scientific method are incompatible
The atheist believed that he had me pinned down because I believe that the scientific method is trustworthy. I explained to him the problem with his argument and why I reject his conclusion (I'll explain that later). I haven't really heard this argument presented much lately. But I did come across it again a couple days ago, not from an atheist but a fellow Christian.
