Most hypotheses about the origin of life on earth state that it arose from inanimate matter. Now, the nucleobases that make up RNA can be built out of the containments of the primordial soup.

the key step to life is a molecule that can rebuild itself. and as we know, RNA-polymerase consists mostly of RNA. these fact indicated that a world must've existed once, where the role of proteins was also taken bei RNA molecules. but this set aside, the essential part is that RNA can be built from ingredients of the primordial soup, and that RNA is the key molecule on the way from inanimate matter to life.
