I think the song represents humanity itself and the conscience to avoid how futile our reasoning can be. We don't want to believe that the world can move on without us, but it absolutely can. We spend all our efforts being competitive and shutting other humans down, but that's not the objective. It's survival. Unless people don't care? Because if we're going to live forever, how are we going to kill each other? And if we're going to kill each other, how are we going to live forever? It's not about the survival of the few, that just reduces our odds. But the sun will still move on.
