Just keep in mind what is "Organic" and what is not. It is all the "difference" here on (our well watered) Earth.
Fixing Occam’s Razor
All things being equal, the simplest explanation is usually the best. But we don’t all agree on what “simple” means.

The headlines always seem to be coming in, with the latest more spectacular than the last. Researchers detect possible signal from dark matter! NASA Rover Finds Active, Ancient Organic Chemistry on Mars! And yet, is there a signal from dark matter that we can go out and measure? Is there anything “organic” happening on Mars at all?
If all you do is listen to the headlines and read the press releases/articles that come out about them, you’ll probably be led to believe the odds lie somewhere between “perhaps,” “probably” and “almost definitely.” And why wouldn’t you? After all, as respects the dark matter signal, you’ll see a graph like this, coming from the scientific paper itself.

Pretty compelling that something’s there at 3.5 keV, isn’t it? Why wouldn’t it be dark matter!
And for the Mars Curiosity rover, that’s perhaps even more compelling. After all, the rover detected a tenfold spike in methane at the same location over a very short timespan, a very interesting find! Here on Earth, methane is produced by living organisms, and then NASA went and released this official graphic.

Water below the surface could have microbes living in it, producing methane, creating pockets of gas that come up through the surface.
How could anything be simpler?
And yet, both of these scenarios are extremely doubtful. It’s probably not obvious to you why it’s doubtful, so let’s show you something where the reasoning — and the conclusions — are more than a little suspect. It’s hard to do better than this argument for dinosaurs on Venus by Carl Sagan.
