We are all stardust.
That oxygen you breath? That comes from dying massive stars, ending their light in a supernova.
The iron in your blood? Some massive stars dying, but mainly white dwarfs, the leftovers of dwarf stars like our own Sun, exploding.
The gold ring on your finger? Mostly merging neutron stars, leftovers from supernovae.
