Kinda humbling seeing that little dot, but like the page said, we are the only planet in explored space that is able to harbor life (at least, carbon-based oxygen breathing life). I think we have a right to be at least a little arrogant about that, don't you think?
I think the only time people are going to keep killing each other and being so territorial is when an extraterrestrial race comes and teaches us a lesson, that we should cherish that which we are given, which is a large and beautiful planet.
