You’re basically saying ‘let’s create some other form that was doing the work’ - which could be true - weird small crevices with certain molecular properties and different metals exposed to heat gradients where ‘the soup’ tidally comes and goes and catalyses reactions - and maybe that was an important step, but you’re also overly easily dismissing something that not only can act as that first step (maybe with some help from some unknown catalyst as a bootstrap) with the added benefit of actual inheritance
