Abiogenesis (Origins)

The problem that exists for abiogenesis, is several fold. Life now---the simplest life--requires 20 amino acids in order to exist. From what we currently know, 12 of the 20 need to be somehow synthesized, but organic chemistry under the conditions currently inferred to exist result in an impossibility, precisely because certain catalysts are necessary.

We have 20 left-handed amino acids that are essential for life as we know it. Since organic reactions make resultant products that are 50/50% right and left-handed we can't use half the product. But we'll skip that issue. What has been discovered by computer analysis is how special are the 20 a-a's we know about? The authors conclude that the 20 are perfect, and were selected by natural selection. (Of course, what else could do it if you are a Darwinist.) Problem, we have only found eight of the a-a's in the meteors that have hit Earth, as naturally synthesized. We MUST find the other 12 to show a natural process that could have created life on Earth, an inorganic planet at first after its formation. Of course we could guess that the eight a-a's got together, held hands, and danced around in a circle creating the others.
