Ecclesiastes 3:19-22

Surely the fate of human beings is like that of the animals; the same fate awaits them both: As one dies, so dies the other. All have the same breath; humans have no advantage over animals. Everything is meaningless. All go to the same place; all come from dust, and to dust all return. Who knows if the human spirit rises upward and if the spirit of the animal goes down into the earth?” So I saw that there is nothing better for a person than to enjoy their work, because that is their lot. For who can bring them to see what will happen after them?
