Underground Life on Mars?

The New York Times has a detailed and fascinating article about deep-earth microbes that have been found in mine tunnels.  There are even some tiny worms that eat the microbes.

This is followed about speculation about whether or not life exists under the surface of Mars.  Scientists don’t know one way or another on that question.

The article does not address a related terrestrial question: Do underground microbes create most crude oil, or is it the remains of dinosaur blood and guts?  The microbes may be winning that argument.
