Metabolism before life even came about? What??

Here's an interesting article about the possibility of the Kreb's cycle having begun before life itself had evolved. This alternative to the currently accepted "RNA came first" theory questions how RNA could have evolved before the Kreb's cycle if it needs metabolism in order to be created in the first place. Also, it seeks to address the lack of pressure RNA would have had to evolve enzymes, if it did not metabolize. The original paper is cited at the bottom of the article.
