Hi, World peace is important and we humans should be competitive when we work and not competitive when we kill each other! Instead of, for example, metal and blood (on the battlefields) we should create a civilization of work so that humanity can survive the expansion of the Sun that will happen later. If we can create a way to live in the outer parts of our solar system then we can survive the expansion of the Sun and not be completely eliminated by that expansion!
