If it had organic molecules how can it be sterile? meanwhile: http://library.thinkquest.org/C003763/index.php?page=origin03 "Chemical Evolution The Water Lily Nebula, a location where complex organic molecules are found. Courtesy Bruce Hrivnak and Kate Su Just as life has evolved into a plethora of different forms over an extended time period, the chemical elements which are the building blocks of matter have also, in a sense, evolved since the origin of the universe. Chemical evolution is essentially the process by which increasingly complex elements, molecules and compounds developed from the simpler chemical elements that were created in the Big Bang. Recent astronomical observations have discovered that chemical evolution has even led to the synthesis of complex organic molecules in space, a discovery that could have serious implications on current theories of how life developed." see bold What does this mean, what serious implications?
