Human beings are literally made out of star stuff. Almost all of the chemical elements that make up a person come from the stars. Any element heavier than hydrogen originated in the stars, and we are definitely composed of more than hydrogen.
Calcium, carbon, hydrogen, nitrogen, oxygen and around 60 other basic ingredients make up a human being. Since hydrogen and helium were the only elements around before the stars “cooked” up some more, it’s a safe bet that most of the substance that constitutes the “physical” you comes from the stars.
