Ecclesiastes 3:19-21

19 Man's fate is like that of the animals; the same fate awaits them both: As one dies, so dies the other. All have the same breath [a] ; man has no advantage over the animal. Everything is meaningless. 20 All go to the same place; all come from dust, and to dust all return. 21 Who knows if the spirit of man rises upward and if the spirit of the animal [b] goes down into the earth?"
