Here's the problem , "Under the right conditions".
Think about it.
Here's a scientists response to the metabolism first theory.
However, in my view this and related scenarios (e.g. Smith, Morowitz 2004) are, given current knowledge in the field of chemistry, unrealistic. It is simply hard to see how the extraordinarily high specificity of chemical reactions, required for complex sequences of reactions and metabolism – for the functioning of life –, would in general be possible without catalytic polymers featuring a three-dimensional substrate pocket. These are only provided by a "gene-first" scenario. I have to agree with Orgel when he says (the reverse citric acid cycle that he mentions lies at the center of the "metabolism-first" scenario proposed by Wächtershäuser):
"There is no agreement on the extent to which metabolism could develop independently of a genetic material. In my opinion, there is no basis in known chemistry for the belief that long sequences of reactions can organize spontaneously – and every reason to believe that they cannot. The problem of achieving sufficient specificity, whether in aqueous solution or on the surface of a mineral (6), is so severe that the chance of closing a cycle of reactions as complex as the reverse citric acid cycle, for example, is negligible. The same, I believe, is true for simpler cycles involving small molecules that might be relevant to the origins of life and also for peptide-based cycles."
