Water and oxygen.
Water and oxygen are the two primary requirements for life. I can survive a long time without food (relatively), but only a few days without water. I can't last even a few minutes without oxygen.
If the oxygen trapped in my body was to spontaneously combust, and consume the water in my body, I'd be reduced to nothing more than a pile of ashes.
The late, self-proclaimed atheist, Carl Sagan, used to like to say that "We are made of star dust", referring to the organic elements of carbon-based nature being the results of stellar explosions (Dr. Sagan wasn't really an atheist... he worshiped the god "Chance", and its servant, "Science"). Dust to dust. Made from dust, and returned to dust. Ashes to ashes.
We are made of star ash.
