Evolution

Perhaps because we are born and later die, we perceive life all wrong. In Erutan, our parallel universe, death comes first, and so evolution proceeds from the advanced to the basic. There, men go from complicated organisms that are so estranged from their environment they destroy it, to simpler childlike lifeforms that live in harmony with their surroundings. Go far enough forward and see man become single-cell organisms, atom clusters and eventually black matter, the life force of the universe. Could be ours is the shadow world, ours the abberation.
