ABSTRACT
The Big Bang theory of cosmology informs us ofthe cosmic expansion from an initial 'singularity'; the formation of stars and galaxies as the expansion proceeds; the nucleosynthesis ofthe chemical elements inside stars; the enrichment ofthe interstellar medium with these elements following supernovae explosions; and the formation of new generations of stars, and planets, from this enriched material. Modem chemistry and biology describe the subsequent development and evolution of life on earth, culminating in mankind.
