People are the entities within the universe that create explanations. They are able to explain what raw materials might be transformed into. Civilize n people, creating knowledge, end up becoming literally a force of nature. We will have this profound impact upon everything that we can see around us. And there's nothing that the laws of physics, the laws of chemistry, or even the laws of biology can predict what is going to happen in the future. The attempt to predict the future growth of knowledge is impossible. That's the nature of knowledge because knowledge creation is genuinely an act creation. It is bringing something into existence that wasn't there prior.
