Scientific paper

Current thinking on the origins of life on Earth are reviewed and the plausible impact of the study of Titan chemistry on this field is discussed. On the primitive Earth, in the presence of liquid water, prebiotic organic chemistry starting from simple reactive molecules or their oligomers, allowed the emergence of life. On Titan, with very low temperature conditions, chemical evolution is still going on, but in the absence of liquid water. However, both environments and chemistries have close similarities and involve a subtle coupling between different parts of their 'geofluid', and two complementary classes of organics: simple volatile and reactive organics compounds and their nonvolatile solid oligomers.
