@1pckt@MaxDWolf@Gutsick_Gibbon I haven't claimed the problem is solved. It's not.
The difference is that origin-of-life models are scientific hypotheses that make testable predictions and are revised or discarded based on evidence. That's not the same thing as accepting them on faith.
@1pckt@MaxDWolf@Gutsick_Gibbon Does the fact that a research program hasn't yet solved a problem demonstrate that every competing natural mechanism is impossible, or does it simply mean the problem remains unsolved?
@1pckt@MaxDWolf@Gutsick_Gibbon The point of many origin-of-life models is that replication itself emerged gradually. Once you have molecules capable of imperfect template-directed copying, you have heritable variation and selection at the molecular level—even if you don't yet have modern cells.

@1pckt@MaxDWolf@Gutsick_Gibbon A stepwise process isn't "a slower route to the same search" if the intermediate steps change the problem. The whole point of those models is that complexity emerges gradually rather than requiring a complete genome to appear in one event.
@1pckt@MaxDWolf@Gutsick_Gibbon You're still assuming the objective from the outset is a modern bacterial genome. That's exactly the assumption I'm questioning.
@1pckt@MaxDWolf@Gutsick_Gibbon Higgs & Lehman's review The RNA World: molecular cooperation at the origins of life (2015) discusses how RNA could both store hereditary information and catalyze reactions, along with mechanisms for replication and the emergence of molecular cooperation.
@1pckt@MaxDWolf@Gutsick_Gibbon Orgel writes that the central problem is understanding how a protein-free RNA world became established on the primitive Earth
@1pckt@MaxDWolf@Gutsick_Gibbon Leslie Orgel's review Prebiotic chemistry and the origin of the RNA world (2004) is explicitly about how informational polymers could arise before modern cells.
@1pckt@MaxDWolf@Gutsick_Gibbon Many models investigate the emergence of heritable information in pre-cellular systems. Whether you choose to call those systems "alive" is a separate semantic question.
