Ecclesiastes 3:18-20

I said to myself regarding the sons of men, “God is surely testing them in order for them to see that [by themselves, without God] they are [only] animals.” For the [earthly] fate of the sons of men and the fate of animals is the same. As one dies, so dies the other; indeed, they all have the same breath and there is no preeminence or advantage for man [in and of himself] over an animal, for all is vanity. All go to the same place. All came from the dust and all return to the dust.
