Interestingly enough, there's been research that backs up the idea of life coming about underground[1] rather than in surface oceans and lakes.

It's especially interesting once you consider that under high temperatures, nitrogen reacts with hydrogen to form ammonia and with oxygen to form nitrous oxides.  Trapped underground, those gases would have been ideal for the formation of DNA-like molecules, and eventually life itself as DNA and RNA reacted with its environment, protected from the hostile conditions at the surface by a thick layer of earth.
 1. Even more interesting, I wasn't aware of it until it occurred to me to wonder about how DNA-like molecules would break down in the absence of life.
