Ecclesiastes 3:20-22

New Century Version

²⁰ Both end up the same way; both came from dust and both will go back to dust. ²¹ Who can be sure that the human spirit goes up to God and that the spirit of an animal goes down into the ground? ²² So I saw that the best thing people can do is to enjoy their work, because that is all they have. No one can help another person see what will happen in the future.
