Origin of life hypotheses postulate prior formation of some minimum set of molecular components by strictly abiotic processes. In most cases, the spontaneous synthesis of organic compounds of considerable complexity is proposed. Knowledge acquired over the last 40 years of stellar, interplanetary, and planetary processes now allows us to place organic chemical evolution in a cosmochemical context in which each of these locales plays a unique and significant role in the development of organic structural complexity. The organic matter of carbonaceous chondrites provides important insights to these processes by bridging the gap between stellar and interstellar chemistry, and the final steps that were played out on the surface of the early Earth. The study of these primitive meteorites allows us to see how stellar and interstellar processes are made manifest in/on planetary bodies and also provides a data base which might prove useful in extrapolating toward the as yet uncharted territory of a pre-RNA world.
