[[the argument is made that it’s “mathematically proven that evolution is impossible”, based on probabilities of molecules arranging themselves in certain ways without some externally directed force being applied with specific intent.]]
Minor point here- it’s not some ‘outside force’ guiding hte system- it’s intenral infromation guiding the binding- if the info isn’t correct in the two parts that coem into contact, they will not bind- there needs to be a system of ifnromation already present, and a higher system of metainformation to ‘conduct’ the whole process in a way that keeps everythign functioning correctly for the species to remain fit- it’s not like it all happens by a force pounding square pegs into round holes
That sounds like a "model".
