To help replicate Several Billion years of chemical combinations and conditions... any extant combos are fair to use.
The infinite amount of conditions over that period and every thinkable condition/combination is fair to try.
Especially those that we are all made up of and ingest to live.
And there are many molecular tendencies. As simple as bonding (O2) or the formation of Crystals, etc, etc.
And there similarly are naturally occurring more complex molecules that have tendencies to organize in certain ways in the presence of others and other conditions. Erath 3.5 Bil yrs ago (first known life) was very different than today.
To reproduce early earth conditions which no longer exist, it's perfectly fair to do so in a lab.
And that's what Miller-Urey did, and did successfully.
Wiki: The classic 1952
Miller–Urey experiment and similar research
demonstrated that most amino acids, the chemical constituents of the proteins used in all living organisms, can be synthesized from inorganic compounds under conditions intended to replicate those of the early Earth. Scientists have proposed various external sources of energy that may have triggered these reactions, including lightning and radiation. Other approaches ("metabolism-first" hypotheses) focus on understanding how
catalysis in chemical systems on the early Earth might have provided the
precursor molecules necessary for self-replication.

This is well more coherent (and justified by the fossil record) than an Impossible/Laughable singular Genesis creation event, or a blundering trial-and-error 3 billion year (ID-not/Engineered-not) version of that goofy myth.
And let's be clear, you are a [specific religion] nut trying to justify scientifically any god, to be able to hold onto yours.
Of course, you have NO evidence, no one ever has, and your are going nowhere with your wittle philosophical clap trap version of God of the Gaps/the GodDidIt Fallacy. (aka Argument from Ignorance)
Laying aside your imbecilic notion that biochemistry is abiogenesis, your fantasy that we are somehow closer today to achieving that which is manifestly impossible (i.e., demonstrating/observing abiogenesis in the lab or anywhere else), indeed, your delusion that we are any closer today to explaining how the mere chemistry of nature arranged the prebiotic, organic precursors of life to produce anything more than a dead-end pile of organic gobbledygook than we were 70 years ago, your failure to answer my question regarding the origin of the self-replicating catalytic amyloids (peptide enzymes), your failure to answer my questions regarding the origin and identity of the even more complex compounds that produced them, your false and boorish ad hominem, your feloniously abject contention that the Miller-Urey experiments reproduced early-earth conditions. . . .
(By the way, a warrant for your arrest has been issued for the latter, and I'm about to serve it.)
Well, since you want to discuss Miller-Urey, let's start here. As I need not repeat myself, the following is copied-and-pasted from my (Michael Rawlings', a.k.a., Ringtone's) article "
Abiogenesis: The Unholy Grail of Atheism".
The underlying hypothesis of Miller-Urey has been falsified for years. Also, the experiment’s conditions were shown to be incongruent and the results, negative. The reasons for this are legion and complex, yet textbooks continue to relate this experiment with the same sort of fanfare in the above as if it were still something more than a historical footnote. An avalanche of innumerable Internet sites—most of them that of atheist know-nothings—continue to tout it as being something that still matters along with theory that is years, even decades, behind current science.
For example, it doesn’t appear that . . . [abu afak's] source knows that the Earth’s atmosphere was oxygen-rich much earlier than he supposes, generally more oxidizing than reducing—necessary for life, but not friendly to the formation of amino acids. In other words, the actual conditions were considerably more hostile to the prospects of abiogenesis than those of the Miller-Urey experiments. The primordial soup keeps getting driven deeper and deeper into the ocean, where, once again, another battery of problematic conditions confound the imbecilic notion of chemical evolution. . . .
. . . What was actually produced in the published Miller-Urey experiment of 1953 were 5 amino acids (3 of the 20 fundamentals of life) and the molecular constituents of others. The dominant material produced in the experiment was an insoluble, carcinogenic mixture of tar—large compounds of toxic melanoids, a common end product in organic reactions. However, it was recently discovered that the published experiment actually entailed the production of 14 amino acids (6 of the 20 fundamentals of life) and 5 amines in various concentrations. In 1952, the technology needed to detect the other trace amounts of organic material was not available. But the unpublished Miller-Urey experiments conducted over the next several years show that a modified version of Miller’s original apparatus featuring a volcanic-like, spark discharge system, which increased air flow with a tapering glass aspirator, produced 22 amino acids (9 of the fundamentals of life) and the same 5 amines.
Question,
abu afak: what of ultimate significance, precisely, did the Miller-Urey experiments falsify relative to their underlying hypothesis?
