Right, that's an implication of science and of philosophical naturalism.
I don't say our mortal lives can necessarily be vindicated, so that we turn out to be something other than absurd by-products of a monstrous cosmic unfolding. But the existential problem remains of how we should reconcile ourselves to the ghastly objective facts. Saying the words you said is easy. Feeling they're sufficient to quell our horror in our moment of dying is likely hard. Hence our reason is complemented by our penchant for story-telling.
Stay tuned for my next article, "Reckoning with the Horrors of God and Nature," which will go into this a little further. And there's lots more to say on this question, of course.
