I will it to be sacred, because this is a choice.
I had this same exact thought a few weeks ago. Although, I have to disappoint you: it was in regards to humanity specifically
Perhaps life is not sacred. I believe it is. Not because I see evidence for its sacredness. Not because I think this is the most logical course of thought. Not because I think this state is conferred by the natural world.
Rather, because I choose to. Even if we were to somehow prove the universe to be entirely materialist, I would still behave as if it were not. Not just behave, either; believe, as well. Even if we somehow knew, objectively and absolutely, that God and soul and importance and beauty are completely erroneous concepts no matter how they're formulated, I would still believe in them all.
This is, I admit, essentially taking pride in a dissonance between what is real and what is accepted. I also realize this is the main problem in sinister -i.e., left-leaning- ways of thought. The key difference is that, unlike the liberal's, this approach to life does not need to claim reality has re-aligned itself to my desires in order for me to have them. A liberal does not demand that society change itself according to his vision of utopia simply because
he personally wants to control society. That would be too... authoritative. Monarchical. Will-driven. Masculine.
Of course, this is the only actual motivation behind his demands; it is the only actual motivation behind ALL such demands. But because he is so terrified of POWER, because he sees it as intrinsically flawed, he cannot accept such a motivation in others - leading him to be incapable of accepting it within himself either, as that would be hypocritical. So instead, his demands become justified by the rest of the world; they are fair, deserved, natural. It does not matter if the world does not actually reflect this; studies will be done, statistics quoted, exceptions pointed out, and metaphors made. All in an effort to prove that the natural, amoral world reflects his opinions of what he deserves.
Unfortunately, this makes it a lot easier for most people sitting in the middle to be convinced by the sinister ways than by the righteous. The left puts a lot of effort into distorting our image of reality, giving the impression that reality does support its methods of thought. It does this by default; it is completely necessary to liberalism, because liberalism is by definition a search for change - not an embracing of what is, but a rejection of it. Only it cannot admit that outright.
So the liberal's dissonance is hidden, unrecognized, and even denied. The dissonance inherent to my way of belief is openly acknowledged and understood for what it is. I do not require the universe to agree with me, in order to believe what I do. That is the blessing I have received as an occupant of the brotherhood of man. That is the unique and utterly salient power I possess as a human - the power to move beyond the realm of what is. The trick is to not to hate existence as a result, and thus imagine it to be something it is not.
