Well, well. It seems the19th century ideas of Mars being a dying planet were rigt after all, if off by a few million (or possibly billion) years.

Point of clarity, organic matter does not actually imply life - it is thought that some comets will be fairly rich in organic compounds.

(To a chemist "organic" just means 'based on carbon 4' - e.g. methane [CH4] is organic regardess of whether it comes from animals or a chemical reaction in a lab.)

I see your point, and raise you Barsoom.

I believe I've seen some theories that life started on the Earth after some sort of stuff like lightning or intense solar radiation caused existing organic chemicals to start going beyond chemical reactions to a stage that would be regarded as simple life.

So I guess that, even if they don't find life on Mars, the presence of organic chemicals shows that the conditions for life might have been met.

That could be important to the people trying to calculate how frequent habitable worlds might be.

If we end up finding organic chemistry on all the worlds in the Solar System, for example, it might support the argument that any planet of similar size to Earth in the habitable zone of a star might be life bearing. :)

I'm sure the people who make science fiction movies will read other things into this discovery. :lol:

I call your Barsoom with Niven's Rainbow Mars - and then fold when someo else throws Podkayne etc into the pot.

I'll throw in Ray Bradbury's Martian Chronicles and C.S. Lewis' Out of the Silent Planet. We definitely can't play this game without them. If allowed, I will add also Orson Welles' War of the Worlds.
Anyway I agree that organic molecules and life are very different things.
