I´ve read into this earlier and i think it falls short in the same way. RNA would never self assembly and the nucleotides is made by living organisms so it had nothing to be build upon. Ribosomal RNA would never self assembly its to complex and it would have no environment to live in, he earth was hot as fuck! No cell membrane or even lipids which could make up membranes.

It would take a lot for life to kick start and nothing in science got a clue of how it started, i find it amazing that life exists against all odds, or does it :) ?
