What I've always thought about is if all life eventually struggles for power and destroys itself? Imaging what would happen if the whole world just worked together! Is this something that is in our DNA, to be on top of everyone? 1% controlling the whole world, limiting their potential... Can we someday put aside our differences and work towards the same goal? Life on earth (humans and animals) don't really work together on a global scale. Is this only because of our nature, here on earth, that we need to destroy thing to live well (coal, forests, animals as food, ...) Maybe there there are planets that have excess minerals, resources to build starships without killing their environment, without the need of wars (for oil for example). Haven't we just had bad luck, being evolved on a planet with limiting resources, or just bad luck that we chose to use limited resources for our civilisation, or just bad luck that we need limited resources to survive? Are there a lot of civilisations struggling with the same problems? Or maybe there are aliens that can just drink water to survive and fly to other suns with just oxygen (just to make a silly example)? This was kind of a response to "Can a civilisation really peacefully exist without destroying itself or the rest of the universe". On the other note, imagination is such a big advantage of humans, we can achieve so much just by using our imagination. Also the whole topic of "Are we alone and where is the rest" is so interesting!
