Abiogenesis Is Impossible

As Pro, my position will be to prove that all (presented) findings regarding abiogenesis either rely on irrelevant scenarios (such as scenarios where certain chemicals that have been proven to have existed billions of years ago are ignored), or produce findings that actually support my resolution that abiogenesis is impossible.Since the rules are to avoid appealing to a negative, this debate will officially begin once Con has made his opening arguments. However, I would like to get one thing out of the way first:I. Problems with the Miller-Urey Experiment. Of all the evidence for abiogenesis, the Miller-Urey experiment is the weakest. However, I have seen it cited as evidence for abiogenesis on DDO, so I'd like to show why it is unreliable so we can move on to more less-looked at evidence for and against abiogenesis.1. Ignored the presence of oxygen.The Miller-Urey experiment utilized the gases methane, ammonia, and hydrogen. However, it ignores the presence of oxygen, which has been proven to exist for 4.3 billion years. [1] When it comes to biosynthesis, "laboratory experiments show that chemical evolution, as accounted for by present models, would be largely inhibited by oxygen". [2] That is to say, oxygen would have destroyed many of the organic molecules created in any sort reducing atmosphere.2. Produced only small amounts of amino acids.The Miller-Urey experiment, while producing more then the 20 amino acids required for life, only produced small yields of these amino acids. The most common amino acids formed were glycine and alanine. Yet glycine made up only 1.05% of the total yield, and alanine only 0.75%. [3]3. Non-existent methane-ammonia atmosphere."...the accepted picture of the earth’s early atmosphere has changed: It was probably O2-rich with some nitrogen, a less reactive mixture than Miller’s, or it might have been composed largely of carbon dioxide, which would greatly deter the development of organic compounds."-[4]Since volcanoes only release carbon monoxide, carbon dioxide, nitrogen, and water vapor, it is now believed by scientists that methane, ammonia, and hydrogen did not make up the majority of early earth's atmosphere [5]. This is also why scientists do not believe that an early atmosphere played a huge part in chemical evolution. [6]4. Amino acids were produced in racemic mix. [7]Amino acids synthesize in both right-handed and left-handed versions. The amino acids required for life are all left-handed (with only rare exceptions), and the sugars required for life are all (with only rare exceptions) right-handed. Any protein that utilizes a right-handed amino acid is rendered useless for life. All experiments to remedy this problem have failed. [8] RNA World Hypothesis. There are various problems with this hypothesis. My favorites being problems with cytosine and ribose, and in addition, a lack of a process to polymerize RNA strands. However, rather then list them all (there are quite a few), I'm going to allow my opponent to make his case and then list any problems relevant to his case.[1] Bortman, H. 2001.
