'Animals' in the Bible

I said to myself, “This happens concerning people, so that God may test them and they may see for themselves that they are like animals.”

For the fate of people and the fate of animals is the same. As one dies, so dies the other; they all have the same breath. People have no advantage over animals since everything is futile.

Who knows if the spirit of people rises upward and the spirit of animals goes downward to the earth?
