The question about life in the universe he said that he thinks that we are the only ones in the universe. That we would’ve seen something! That really confuses me too how is it that we can’t get an image of another planet in a different solar system but say we would’ve seen evidence of structures built in other solar systems??? He also said there may may be single cell but not multiple cell life. I really have trouble believing that the Earth is so special. What if the universe is filled with animals that can’t make machines. Life began here as soon as it was possible, and look at all the different kinds of species. Even after asteroids ☄️ hitting the earth and killing 95% of all life and still life recovered and new species of animals. Maybe super intelligent life is very very rare   Or life like our intelligent life manage to destroy themselves ,but maybe the universe is filled w intelligent animals !! I would love to see what kinds of animals live on other planets. Giants like the dinosaurs or tiny ones like ants ones that live in the air like birds others in water like fish. It’s just so hard to me to believe there’s nothing else in this infinite universe and if it’s true that would really be So Sad and the Universe a waste of Space ! 🤑
