UFO crashed in the mountains

In our galaxy, there may be life on some planets, but not very intelligent. Microorganisms or macros can exist, but we still know so little. And by the standards of the universe, one might say, they were nowhere. Yes, we have not even been on neighboring planets, I mean a person. Although, in order to determine whether there is life there, it is not necessary to be. In the solar system where we humans live, there are no highly developed creatures, here people are the smartest creatures. But there are many stars, even more galaxies!?
