The very fact of our existence is a miracle that causes surprise even the greatest minds. For primordial self-organizing matter is impossible, and hence it spontaneously acquired this self-organizing property which led to the emergence of the Universe followed by the birth of life on planet Earth and the formation of Homo sapiens.
Matter is any physical entity. Matter that has a self-organizing property differs from that which does not, in that this very property enables it to undergo qualitative evolution and, in time, lead to the birth of intelligent beings.
The beginning of time, and consequently the universe — the moment when self-organizing matter spontaneously originated: either it acquired this property that it previously did not possess, or it appeared from the absolute Nothing, if such a thing is possible in principle.
Matter possessing self-organizing property must have a beginning. If infinite space filled with eternal self-organizing matter is possible then there arises a situation where there is an intelligent world that doesn't know its beginning, which is contradictory.
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.
