No matter how confidently you state this, no matter how patronizing of a reply you make to someone who doesn't share your belief, you cannot know this as fact. A choice to believe this is not based on evidence, but faith (or for some, "hope" that they weren't wrong all along).

But as long as you're treating creation right (humans, animals, and ecosystems) then go with peace, brother (or sister).
