Or like saying "look, the monkey can sometimes make small words appear when it bangs on the keys of this typewriter. This tells us something about the origins of novels."
studying the behaviour of a monkey when introduced to a typewriter doesn't. Studying the formation of a few molecules in a controlled environment hardly explains how living forms came to exist.
we made substantial progress in biology before we understood molecules. this is because it's not necessary to be entirely reductive to understand larger systems.
