Big Bang produces bland distribution of H, D, 3He, 4He, and traces of Li, Be, and B isotopes.

First stars and galaxies form (poorly understood epoch)

Massive stars burn quickly and brightly. Becoming unstable, the most massive stars explode as SNe, ejecting newly synthesized elements from C to U

Ejected elements are incorporated into new generations of stars, planets, human beings, etc.
