"My thinking cap is on quite securely. But in the search for the truth why should we insist that the origin of life must be constrained to natural laws? Perhaps this is a subject beyond the scope of the natural sciences."
Now you are thinking. If you believe that God is not constrained by natural laws, then you also must believe that science is incapable of proving or disproving the actions of God. It doesn't mean that science is useless or that God is unknowable, only that science can't prove or disprove that God exists. You know God from the Word.
This is what I have been saying all along. I have never said that the natural science could prove a divine origin of life or of the origin of species. But they could show that as of yet there is no known natural cause. The natural sciences can seek to find a natural cause but must admit the possibility that one does not exist. Science does not equal naturalism.
