Neither have any scientific observations to back them and, as such, are simply theories from which you may select.
LOL. So what was all this business from a thread on ID, how it should not be regarded highly because it was not a scientific theory? So what do you do? Not only do you attempt to misinform and create a pedagogically irresponsible statement, you completely contradict everything that was said in that thread about ID. Abiogenesis is infinitely a greater scientific theory than "god created life." One would figure with the amount of prattling you had on the subject, you could at least understand and acknowledge the scientific credence that should be lent to abiogenesis over "god created life," instead of placing the two concepts at the same level, which is simply incomprehensible. Or does that all go out of the window once the logic enters against your predisposed beliefs?
As posted already in this thread, The Miller-Urea experiment displays a source of amino acids from an abiotic source. Couple to that, the experiments by Oro, further supports the yield of adenosine from simple products that would have been available in the early atmosphere. Why is adenosine important? It plays into the perfect situation, the RNA World Hypothesis. RNA is the only molecule known currently that can catalyze reactions, store genetic information, and have the potential for self-replication. For that reason, RNA and adenosine is so important for the beginning of abiogenesis, as RNA could be the first "living organism" to start on the Earth. Along with the non-oxidative atmosphere, there is strong evidence behind this mindset of the early Earth.
Thus, any statement claiming that there is no scientific observations in favor of abiogenesis is disengenous, and intellectually false.
Furthermore, the statement: "Only left handed amino acids are found in living organisms, and the ones created in the Miller-Urey experiment, and all subsequent experiments, succeed in creating right- and left-handed amino acids in roughly a 50/50 ratio."
is inherently shortsighted. Not only would RNA be the first "living" organism, all it would take is one conformation of RNA to choose a form of amino-acids it binds to in its active site, as it turned out with life, it would have choosen the left-handed form. All there needs to be is an early selective event, thereby addressing your simplistic remark.
