I see many people following the same path here as I puzzled over for a long time. Ancient writers would sometimes invoke some historic person and place words in their mouth to address an issue that could not be addressed otherwise. Now, how many humans are known to have lived before any part of God's law was presented? I will give you a hint, it is a whole number less than 2. Paul was born well after the laws God gave to Noah, for general humanity, or Moses, for the Jews, so how could he have lived before God's law?
