I'm pretty sure there's close to 100% chance there is life in the universe. However, understanding the immensity of the universe is only half of the equation. You also have to understand the incredible sequence of events that got us to where we are. A dual star system would be harder to get life on any kind of schedule. Granted, that's not insurmountable, but think of it. Without migration a lot of species wouldn't exist. Without the core of the planet being so big relative to the planet gives us a huge shield against the sun which gives us life and trulies to kill us. The large moon relative to the planet allows tides among other things. The life before us not only got us here evolutionarily, but also became the fuel to advance society enough to search for other life forms, as well as kill the ones here.
The key difference in what you said is "intelligent life" which would be incredibly rare. Beyond that, you assume that self-destruction isn't tied to the very same thing that gave us intelligence in the first place. And we're not the only animals that are greedy, either. You see it in everything from pets to wild animals and their "pecking order". To say that humans aren't an intelligent species defies all evidence around you, and the only evidence we have of higher species and more advanced societies is sci-fi.
Fuck shows that glorify the militarization of police.
