"and finally, self-copying RNA formed." LOL, do we have an example of such a thing, RNA that can copy itself independently, without helper chemicals/energy? It's quite clear to me that life most likely started with a 'co-operating set' of chemicals that could catalyse each other's reactions, necessarily in the presence of some kind of energy gradient, and that RNA, DNA, etc came after, and even then still rely on the 'soup' of chemicals that they are in, for reproduction.
