Abiogenesis: How did life start on Earth?

Carbon compounds (amino acids, alcohols, formaldehyde, etc.) have been found in star forming regions.
They are also present in meteors, asteroids and comets.
Miller and Urey showed that amino acids could be formed from UV or electrical discharge in the atmosphere of the early Earth.
So far nobody has managed to create self replicating molecules from scratch.
- Earth had millions of years and a lot more organic molecules to do the job.
