Well, if not cynically, said. Let’s not confuse the subject here. Let’s start by defining our terms. Evolution means change over time. Nothing more. It does not pretend to describe origins. It wasn’t intended to do so. It only descibes change that are retained and passed on to future generations of a species.
Stein sought to bring the original source into the argument. This is not evolution. This is also an unsolvable riddle. Organic molecules are created from inorganics routinely as part of the balanced chemical equation of this world - but that does not mean an organic compound = life. Only that a carbon based molecule exists in a transitionary state. Life and how it began is a fascinating topic. But as of yet unprovable by the available science. So we can safely take it on faith that life DID happen and thank God that it did. Evolution, as I said, does not address that. Only how life changed once it got here.
But yes, abiogenesis is an entirely different subject than evolution through natural selection of genetic variation. This is no more a “weakness” of the theory than the fact that the theory of universal gravitation of mass doesn't address the origins of matter.
