Since mars has no active volcanoes (a possible sourve of methane), it's possible that the methane comes from micro-biol activity. That said I personally believe - based on a book I read - that life on Earth actually started on Mars and travelled here as bacteria in space rocks. This is probably how life pollinates planets throughout the galaxy in general.
WASHINGTON – A surprising and mysterious belch of methane gas on Mars hints at possible microbial life underground, but also could come from changes in rocks, a new NASA study found. The presence of methane on Mars could be significant because by far most of the gas on Earth is a byproduct of life — from animal digestion and decaying plants and animals.
Past studies indicated no regular methane on Mars. But new research using three ground-based telescopes confirmed that nearly 21,000 tons of methane were released during a few months of the late summer of 2003, according to a study published Thursday in the online edition of the journal Science.
"This raises the probability substantially that life was there or still survives at the present," study author Michael Mumma of NASA's Goddard Space Flight Center told The Associated Press.
