This question implies that there is anything special about humans at all- or that the universe itself is not simply a huge wonder. Don't you ever sit back and marvel at the fact that everything your are comes from four little molecules? I think that, in itself, makes all life pretty sacred. But to come closer to answering your question- no, matter doesn't loose sanctity when lose from the idea of "sacredness". To be honest, human consciousness doesn't count for much. In the scheme of things, we're just as tiny as an atom is to us. I think DNA is sacred. It's a code that writes everything you are. From the color of your skin to the food you like, your DNA is YOU. Therefore if you are sacred, so is it. You are the sum of your parts. The atoms that have collided and bonded are you, also, and by whatever force that gives you a collective, subjective conscious capable of evaluating the miracle of looking at the skin on your hand and knowing all the cells will have regenerated in two weeks also calls you sacred should acknowledge that even the tiniest parts are important- most important, in fact. So even if sanctity is a subjective idea, you can apply it to everything. The atoms that make you up also make up the door to your house and the rocks, and grass, and trees that sit outside. In this way, science manages to be almost religious. Everything is made up of the same stuff. All life springs from the same chemicals. If that isn't sacred, I don't know what is.
