This whole there isn't Dyson spheres so there's no intelligent life is absolutely ridiculous. You think some highly advanced alien civilization will be using human level technology?  That's like 1000 years ago scientists were looking around and not seeing any messages written on paper just strewn across the galaxy. Must not be any life communicating out there. Now we can just say hey Google call so and so from thousands of miles away and talk to them almost instantly. That's just in 1000 years. Imagine 100,000 years you really think they'll have to get their energy by building this stupidity massive group of materials surrounding their sun?<br><br>It's been billions of years on this planet that life has been here. We are just now able to even look out in the universe. How arrogant is it to think we can even grasp the types of thinks they'll figure out. If that asteroid didn't slam into us and kill all the big dinosaurs then they would still be walking around eating each other. Yes the universe is very big and there will be more advanced civilizations out there but thinking they'll be right next door with a big ass sign saying hey look I'm here is ludacris.
