Observed molecules such as methylamine, CH₃NH₂, are nearly as complex as the AMINO ACIDS which form the basic building blocks of life on Earth.

Hoyle and Wickramasinghe have suggested that life began in giant molecular clouds rather than on the surface of the Earth.

(Hoyle wrote "The Black Cloud" in 1957, a science fiction story in which a cloud containing an intelligent being engulfs the inner Solar System.)

These molecules would not survive the high temperatures associated with the formation of planets, but they could be trapped in COMETS  (icy bodies which originate in the outer Solar System) which eventually crash onto the surfaces of new planets.
