The complex anatomy of humans makes it tempting to think that its random origin is impossible. But it turns out that chaotic and purposeless matter, possessing self-organizing property is capable of forming quite intricate phenomena over time.
Approaching it rationally, we won't find any purpose to the Universe. But through a lens of irony? The Universe might have a purpose only in one case: the emergence of humans is a byproduct of its micro-processes. In other words, it's completely unaware of us. And if we elevate the degree of irony? It also knows nothing about itself.
Could evolution on planet Earth not happen? Yes. Did it have a purpose upon arising? No. So what is it at all? A random transformation of the matter resulting from a combination of circumstances, and for us - pure luck!
For those who wish to ponder the aimlessness of evolution and the probability of the extinction of all living things, modern popular science provides the opportunity to study the events of mass extinctions in the history of life on Earth and the deadly natural and cosmic phenomena.
It's evident that the Universe has no purpose, and it's "morally neutral" towards us. Thus, the concept of a "fine-tuned Universe" should be explained in some way, and the most logical option is the Multiverse.
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.
The evolution factors and mass extinctions in the history of life on Earth point to the absence of a definite aim for the emergence of life and the process of evolution.
The past and present events in the Universe point towards the fact that the extinction of humans, or any other potential intelligent life, in this space desert is a common physical phenomenon.
