Just inorganic material combining at random and eventually, over about 10 billion years, randomly creating something that self replicates in some way, beginning the process of evolution through natural selection and inevitably progressing to life as we know it.

I don't think religion is needed at all for this. I also don't think this has to be a common thing (after all, here on Earth it only happened once, but it's also possible that once life is widespread it makes it very difficult for emergent new forms of life to take off).
