We know so little about the world that surrounds us. Mankind seems to be ancient and wise. But in reality, in the face of the universe, we are just babies. Are there other worlds? Undoubtedly! We do not know anything about them, not because they do not exist, but solely because the universe does not allow us to go there. As I have already argued, humanity is just a baby if you look at it on a planetary scale. But you will not let a baby into, for example, a chemical laboratory! So they don't let us in.
