Really? I would like to see the support of this. I was under the impression that any amino acids formed naturally would be oxidized by oxygen in the atmosphere.
The Murchison meteorite shows evidence of amino acids which have formed extraterrestrially. Surely that is a natural process. And, as pointed out by Abby, there is evidence that there was only minimal oxygen in the early earth's atmosphere.
