Somehow, the article managed to miss what should have be a big part of the announcement. They found evidence of kerogens. That has a bit more impact.

  So... I didn't know what kerogens were so I looked it up. Classified as solid organic matter in sedimentary rock. It is formed by the degredation of living matter. So wouldn't this discovery relating to Mars further hint that it may have supported life in its past?

    Why only in the past and not in the present? Methane could be produced from living organisms.

    I’m curious about that as well. The wiki showed that kerogen looks very similar to chlorophyll. So how is it not safe to conclude it was made by life? Are there any non living sources of it?
