So what do you think about aliens and other intelligent species (and not bacteria), do you think they exist somewhere? I'm sided more with their existence, our universe is far too big for there not to be IMO. If you think about the creation of earth and evolution of humans, how can the same thing not happen on other planets? There are millions of them, after all. A theory I quite like the idea of is the zoo hypothesis, it sounds like something us humans would do, and assuming these other species are as intelligent as us, or more, they would too. What's your opinion?
