I don’t mind the idea of amino acids forming in some pool and sticking together to make peptides. I don’t mind the idea of purines and pyramidines forming in some other close by pool and sticking together with some sugars that have formed there, and some phosphates that are hanging around, and producing short strands of self-replicating nucleic acid.
I’m just wondering how the nucleic acid started making protein - where did the enzymes come from? I don’t think the protein pool could have made the right enzymes. And how does the nucleic acid get long enough to code for proteins with no enzymes? How do you make proteins without rRNA, mRNA and tRNA and why would you have them before you made proteins?

Here is a short and simple speculation on how amino acids currently form in space. The 3 most common amino acids are formed floating in molecular clouds and on the surfaces of meteorites. In fact all the building blocks of life are found in space, including fatty acids and sugars.
It seems probable that these could also have formed on the surface of the earth 4.5 billion years ago. The hard part is figuring out how to get from building blocks to whatever early life-forms might've been like.
