Overall, science confirms the following assertions: humans aren't the only sentient entities in the Universe; the extinction of intelligent life is a natural, ordinary phenomenon; life on Earth might never have emerged and can vanish at any given moment. What's the conclusion? The Universe exists just because, without any inherent purpose. It is not designed for the emergence of intelligent beings. We are the result of a chaotic transformation of matter, and every day we advance in our understanding of the world and ourselves.
