How did these simple organics come to be on these bodies in the first place? Were they indigenous? Or were they deposited by impacting comets together with large amounts of water?
Scientific opinion is shifting towards the view that comets have played a significant role in seeding the chemical building blocks of life. "An impacting comet has the power to destroy life on Earth, but we now think that comets may have also helped to create life in the first place," says Gerhard Schwehm, ESA's project scientist for the Rosetta mission.
