As one dies, so dies the other—they all have the same breath. Man has no advantage over the animals, since everything is futile. All go to one place: All come from dust, and all return to dust.
Actually, it isn't. The book of Ecclesiastes, which you quoted, goes very much against the grain of the rest of the Bible, which generally tends more towards the idea that man is distinct from the animals, and does have a higher purpose, which is to serve God. Ask any Bible-thumping evangelical and they will be very quick to tell you that all do not go to one place, because their whole raison d'etre is to persuade you that if you don't follow exactly whatever particular flavour of Christianity they are pushing, then you will end up going to a very bad place indeed whereas they, of course are already assured of their entry into a not-so-bad place for all eternity. They will also tell you that the Bible never contradicts itself. I leave you to draw your own conclusions.
You sir, are a genius. I love that wording. That should have been on the welcome brochure we all get as babies, assuming we could read it.
