Good catch. I'll rephrase my question then:
Can life come from non-life and only the natural progression non-life carries out by itself? Is life self-organized?
I will grant that the revised question is an open one. It is an assumption of science that a materialistic explanation can be found. Of course this assumption applies to all areas of science, not just abiogenesis. Science would not be possible without this assumption, since if we don't assume that the universe is explainable, there's little point in searching for explanations. If the origin of life actually does require Divine intervention, then science will never come up with the right answer.
