This chapter summarizes key themes and presents some final thoughts. It argues that Earth as a planet has the “right stuff” to be an oxygen-accumulating planet. Having the right stuff, however, is not enough. For oxygen to accumulate, it has to be produced, which means that oxygen-producing organisms must first evolve. On Earth, the pathway to the evolution of oxygen-producing cyanobacteria was quite a convoluted and complex process. The chapter asks, if history would repeat itself, would the outcome be the same? Would cyanobacteria have evolved in the same manner? Would coupled photosystems have emerged in the same way, or at all, or would something different have taken its place?
