This song is about the meaning of the existence of humanity.I take the lyrics in a rather literal sense. In this lignt I think the first half is very touching, though the last half is a bit strange.
The universe, including everything human, will inexorably disappear when the sun burns out. The sun is a star so it has a limited lifespan (though very long compared to the life of a human being of course). So there is a time in the future when the sun will burn out. When that happens all memories of humanity as we know it will disappear, therefore nothing that happened before will matter anymore.
By the way the last line is "I will remember us and wonder who we were."
