This is up for debate.
Not really unless you have evidence beyond the tired and absurd "It's complex therefore it was designed". If you do I'd love to have this debate.
You personally BELIEVE that God had nothing to do with it.
I personally don't see why a god of some kind had to have anything to do with it. Very big difference. I'm sure many on here hold this position.
So I suppose if I threw a rock off a mountain, then hiked down, there would be a brand new Ford F-350 waiting for me at the bottom,
If this happened I assure you I would rethink the super natural and god belief. This is not possible and this compared with observed natural processes is laughable.
