Why are we considered star stuff?

Answer 1

We are made out of heavy elements that are usually created in a supernova. Normally hydrogen and helium (light) are the abundant materials in the universe (barring exotic and unexplained material) with heavy materials coming from high energy explosions (supernovas.)

Answer 2

When a star goes super nova (meaning it explodes) it produces heavier elements such as Carbon, oxygen, and nitrogen, The stuff that is in your body, eventually those elements find their way into a planet and life arises from that eventually.

Answer 3

We are considered "star stuff" because the chemical elements in our bodies, like carbon, oxygen, and iron, were forged in the cores of stars through nuclear fusion. These elements were later dispersed into space when those stars exploded as supernovae and eventually formed new stars, planets, and life, including us. Essentially, we are made of the same building blocks as the stars themselves.
