Robert Hazen proves that the earth has an average composition of minerals of a planet in an average solar system throughout the universe.
The point is that bio-chemical molecules already form in cosmic clouds, due to radiation.

Abstract
Astronomical observations have shown that carbonaceous compounds in the gas and solid state, refractory and icy are ubiquitous in our and distant galaxies. Interstellar molecular clouds and circumstellar envelopes are factories of complex molecular synthesis. A surprisingly large number of molecules that are used in contemporary biochemistry on Earth are found in the interstellar medium, planetary atmospheres and surfaces, comets, asteroids and meteorites, and interplanetary dust particles.

Current challenges in astrochemistry are discussed and future research directions are proposed.
