Why discovering organic molecules in the Solar System could indicate the existence of extraterrestrial life

The past month has seen several fairly major developments with regards to the discovery of organic molecules at different locations in the solar system. First NASA announced the discovery of variations in methane concentrations on Mars, followed by the discovery of organic molecules in Martian mudstone. More recently it was revealed that the Cassini probe had observed even more massive organic molecules on Saturn’s moon Enceladus. What is it about these discoveries that point to the possibility of life elsewhere in the Solar-system? 

Following the discovery of methane in rock and soil on Mars earlier this month it would seem that the solar system's previous most likely seat of life, Saturn's moon Enceladus, wasn't quite ready to relinquish its title so soon. Spectral analysis from NASA's Cassini probe has revealed the presence of complex organic molecules ejected from the moon's icy surface, it was announced in a press release today. And in the fashion of true one-upmanship, the molecules found on Enceladus are over ten times greater in mass than methane.
