how do you we know that the gases found on Mars and Titan were not from a biological source?
My guess is that they were not because there is no evidence of organic life or prior life on these planets and moons. I'm open to the idea but I believe the idea of life on these planets and moons is highly unlikely.
Anyway the idea that carbon/hydrocarbons are unique to this planet due to life seems kind of myopic and ignores the fact that elemental carbon is formed from the stars (iron being the last element in a dying star). With the right combination of pressure, temperature and time elemental carbon combining with hydrogen to form hydrocarbons abiotically does not seem that far fetched.
