We are all stardust.

The oxygen you breath? That comes from dying massive stars, ending their life in a supernova.

The iron in your blood? Some from massive stars dying, but mainly fron white dwarfs, the leftovers of dwarf stars like our own Sun, exploding.

Carbon, the basis of life? Mostly from dying low mass stars.

The gold ring on your finger? Mostly from merging neutron stars, leftovers from supernovae.
