Good point, but I disagree; I actually adhere to one of two theories - panspermia or ribozymic origins. However, even panspermia does not in fact answer our question of origin.
I believe that life is just an emergent property of the universe - possibly much more common than we may think. There have been some experiments done on ribozymes but I failed to link to any serious articles previously here are some to get you started:

The fact that the Earth was incredibly hot is not up for contention one does have to admit though that if life eventually came to live on Earth these conditions must have changed. I believe that after significant cooling the Earth became apt for the 'creation' of life.
