Of a 70 kg body, 45.5 kg is oxygen and 12.6 kg carbon. Everything except hydrogen was forged inside stars.
Within three minutes of the beginning, hydrogen and helium existed. That was all. No carbon, no oxygen, no iron.
Oxygen is 65% of a 70 kg body. It was fused from helium in stellar cores and scattered by supernovae.
The triple-alpha process binds three helium nuclei into carbon. Without it, carbon-based life could not exist.
Gold and uranium are not made by a star living its life. They require supernovae or neutron-star collisions.
