They could have likely come from comets. Doesn't indicate that they ever developed any further.
But, there are probably hundreds/thousand/millions of planets and satellites that have much more favorable conditions for those molecules to develop.

A European Rover will be able to drill 2 meters down! Hang on when that happens! They will be able to analyze material that hasn't been degraded from radiation and other forces.

They also found seasonal Methane in the thin atmosphere! This is exciting stuff!!

because they thought the experiment was flawed or the results could be explained in a non-life way.

I actually worked for the scientist Gil Levin who designed the experiment many years later in the 1990's.

He was a bit of a crazy genius but I believe he was right and did find life. I reviewed the data and the reports and it looked legitimate to me. I am PhD biologist.

He is still alive and trying to find a way get another experiment on a Mars mission to prove his initial experiment.

Maybe if Levin tells IQ45 that he thinks Obama's DNA originated on Mars, trump will fund his mission.

As far as we can tell, life as we know it always produces CHON molecules, but CHON can also be formed by other than living processes. An excavator and a good chemistry lab would be helpful.

Panspermia (from Ancient Greek πᾶν (pan), meaning 'all', and σπέρμα (sperma), meaning 'seed') is the hypothesis that life exists throughout the Universe, distributed by space dust, meteoroids, asteroids, comets, planetoids, and also by spacecraft in the form of unintended contamination by microorganisms.

https://en.wikipedia.org/wiki/Panspermia


Or, at the very least, that life is inevitable wherever conditions are right.

We are not alone in this universe, but the distances are immense, and "intelligent" life forms such as ourselves exist for mere moments, becoming extinct, or becoming incomprehensible and unobservable to creatures such as ourselves.

There isn't a damn thing in any cell (as we understand them), that ISNT causally determined. So given the correct conditions that give rise to that determinative outcome, it's a foregone conclusion that life would exist.

A full understanding of those (possibly) highly variable conditions, will require at least one more example than we currently possess.
