Miller-Urey is taught to school-kids and college students without 4 key bits of data
- When amino acids in solution are sparked they break-down and so a reservoir was included in Miller’s 1953 apparatus, out of the system loop, to protect any generated amino acids from breakdown via the week long sparking of the CH4, H2, NH3 gaseous, and water vapour, mix.
- Miller’s 1953 experiment only produced 11 out of 20 necessary amino acids and the experiment wrongly excluded Oxygen which the earth had.
- Miller’s experiment produced a 50/50 mix of L and R handed amino acids, the R hand versions of which stop any possible synthesis of cellular protein, all of which are essentially L handed. No follow on experiment in the 65 years since has produced cellular type proteins.
- Miller’s yield of amino acids (among the gloop of tarry carcinogens) was tiny: 1.05% glycine and 0.75% alanine, with traces of 9 and another 9 missing altogether.

Of course there was a reservoir. The experiment tried to mimic actual conditions. And any compounds generated would settle out. Why would you continually pass exactly the same amounts of gas plus any compunds generated through the same system?
The experiment produced 22 amino acids. Not 11. His results were tested again in 2008 with, obviously, much more accurate equipment.
So what if it produced a mix of left hand and right hand amino acids? As long as right handed are produced it could lead to protein. That’s like you saying that if half the people in the world are infertile then no more children will be born.
And the experiment didn’t set out to produce a set amount of anything. Saying that it failed because there wasn’t much is just you setting your own personal limits. You could make the same accusation however much amino acid was produced. Hence your comment is irrelevent.
