I am fed up to my eyeballs (and now, it seems, fedr808 up to my eyeballs) with this persistent misunderstanding of the relevance and misinterpretation of the results of the Miller-Urey experiment.
The experiment used a reducing atmosphere. There is now general agreement that a reducing atmosphere was not present on the early Earth.
The experiment produced only five amino acids with pretty low yields, not the fourteen or fifteen you are claiming.
The importance of the experiment was that it represented a change in mindset in relation to the origin of life, demonstrating for the first time that it was feasible to investigate that origin experimentally. That makes it a landmark experiment. The actual results are disappointing and largely irrelevant.
My apologies than. Butyou gotta admit, 5 is a definite start, and considering that the earth is around 2-4 ish billion years old (Im pretty sure), that seems to give a lot more time to develop a couple more amino acids.
I think the results are significant.
It shows that there is irrefutable proof that evolution can happen.
