It is likely that a combination of exogenous and endogenous sources contributed to the synthesis and accumulation of the building blocks of life on the early Earth. It may even have taken several starts before life surpassed the less than ideal conditions at the surface. The importance of comets for the origin of life on the Earth has been strongly advocated for several decades. We review the historical development of this idea, the collisional history of the early solar system, and the role of comets in delivering a large fraction of volatiles and intact carbon compounds onto the early planets.
