You are setting an almost impossible standard. Whatever direct evidence of abiogenesis there was is surely lost now. I can't even begin to imagine the circumstances required to fossilize and preserve protocellular material for >3500 million years in the earth's ever changing crust.
Not 'almost'. It is impossible to find evidence that isn't there.
All the evidence that we have is for a Biotic Period, abeit a very early Biotic Period.
According to the Postulate, there was a period of 100-500 million years wherein life arose from the 'Prebiotic Soup' - but there is no evidence of the broth, not a noodle.
So you actually agree that you have set an impossible standard in asking for direct evidence for abiogenesis?
Yep.
How about indirect evidence, like for the 'Primordial Soup'?
That would be a meal long since consumed but the stains don't seem to have wasted out.
