I strongly object NP. We know HOW it happens but we do not know the WHY.
Our planet is alive, that is why.
Interesting point and one that is not in conflict with Faith.
I think that asking 'why' is a pointless question for the most part. The sky is blue -why? Well, I know the scientific answer about the refraction of light, do we need to know 'why'? Would you feel better if you 'knew' that God perhaps preferred blue over red? It is what it is.
We have learned that the universe itself is 'alive' in that it is not static in its orientation and composition. To have faith do you have to know 'why' this is so? I don't think so.
If you have faith St. Paul's words should put to rest the need to know the 'why'. "For now we see in a mirror dimly, but then face to face; now I know in part, but then I will know fully just as I also have been fully known."1 Corinthians 13:12
Concentrate on the now and the things that you have the ability to confront and make for the better. To much emphasis on the 'why' will only lead you to despair.
