I have a story that involves angels. My problem isn't one of risking offense, but of bad internal logic to the plot. In the story, I have a few angels who are capable of creation (life, not just objects). While there is some playing around with religions, for the most part I'm going by historicity and as old as I can get of origins, not fantasy to drive the logic of the world. Any ideas how I can make this world without looking like it's just random?
