It must be very selfish and presumptuous of us to think that we are the only human beings in the universe. What's more, I have a feeling that we are just one tiny part of the universe. There is a famous anecdote by the singer Andrés Calamaro who claims to have seen a UFO. Just like him, many other people have said the same thing and can even describe the experience. There is a famous belief that we are only someone's dream, and when that person stops dreaming, we will disappear. Greetings, @dedicatedguy
