The origin of life includes more possibilities than the “primordial soup”.
Primordial soup is anything with amino acids. What else do you have?
OK. I didn realize the definition was that broad. But the thing is..the earth is lousy with amino acids right now. Magnitudes more concentrated. And we never see new life forming. It cant be a game of odds because it happened in a geological eyblink after the earth cooled. Almost as if it were inevitable. But never again despite an Earth becoming increasingly sodden with amino acids?
There is something interesting in that alone.
That's a good point you bring up about the magnitudes of amino acids. I never thought of the times they were plentiful and times that weren't. Trying to discuss things with atheists, we never get that far in our discussion before ad hominems

.
I suppose the abiogenesis argument is that they're here, so why couldn't they have formed in primordial Earth? I don't think many scientists believe the prebiotic gases used in Miller-Urey experiment were correct anymore. Yet, I think that's still their main starting point and argument for amino acids on primordial Earth. IOW, there hasn't been a newer experiment with different gases.
The abiogenesis argument is not an argument at all. We know with
absolute certainty that biological life from basic building blocks of chemical compounds took place. Either it was naturally occurring or it happened by super-magical means. We have no evidence for Amun-Ra magically starting life and we have no evidence that gods with talking pet snakes created all of existence 6,000 years ago. That tends to narrow the field to the most likely, most studied scenario where life developed due to interactions of chemical compounds.Primitive protobacteria of simple molecules slowly evolved into more cooperative self-replicating systems, then finally into simple organisms.
For all the appeals to magic and supernaturalism, it is scientists in the relevant fields of chemistry, biology, paleontology, etc., who are doing the research. The charlatans at creation ministries are doing nothing but making every attempt to discredit researchers because the religious extremists have their scared cows to protect.
