They possibly detected dimethyl sulfide, which is only known to be produced by living organisms.

only know to be produced.....is a whoa bessy phrase,?¿ as in 70 years ago an undergraduate figured out that dimethyl sulfide was produced by living organisms and he asked his professor what else made it, and got shrug and "nothing else I know of" and everybody has been cutting and pasting since, OR, an international team spent years and millions working on the chemistry behind dimethyl sufide in an epic known to all quest to determine it's origins. Science does have an issue with cutting and pasting ancient mistakes, and then bieng exceptionaly reluctant to change and move forward, not to mention that SETI, and the rest of "alien" research is most definitly tainted with public fantasy and entertainment industry influence, so even with one of the notoriously oderiferous sulfide compounds present, I wont hold my breath
