It seems to me that we are not alone in the universe, that anywhere else in the depths of intelligent civilizations there, but we did not find them, just as they have. makes me think like simple common sense, because the universe is infinite, and somehow not particularly believe that at such vast expanses we were unique. still, if somewhere arrived here the seeds of life on planet earth, then perhaps it could fly and somewhere else. conditions are the same as exist on our planet, the path of evolution, which took the planet and our solar system, they are not unique to the universe. certainly, there are in our galaxy, or in a neighboring galaxy something. so even a simple probability theory speaks for the fact that we are not alone in the universe, and somewhere there is still our brothers in mind. we may be lucky, and we meet with them, and may not be lucky, maybe it will happen in a thousand, two, a hundred thousand years. across the universe is an instant, that all these years, and for us, of course, many generations of life.
