There is no meaning in asking whether it&#x27;s true or not, because &quot;chemical reaction&quot; is a model we create, a map describing territory. In no way is the &quot;universe is a big chemical reaction&quot; more &#x27;true&#x27; than &quot;universe is composed of stars, stars have planets around, at least one planet has life on it&quot; than Pale Blue Dot is more &#x27;true&#x27; than Google Maps. Different maps, same territory, and the only thing that matters is which one is more useful for given purpose.
