As an aside, when reading this I considered a fun alternative theory (I'm not actually proposing it as any kind of truth) that if it's ultimately discovered that the processes behind the creation of life are just too complex to be duplicated in our universe... ...Rather than invoking a god which comes with its own problems (i.e. who/what created the creator) one could infer that life came from a universe where the physics/conditions for creating life are possible, and life somehow crossed branes moving from one universe to the next. Consider a reverse/inverted universe where instead of space being a void, space is solid containing voids/cavities/pathways between voids, allowing complex chemical processes to occur naturally and at great scale.
