Life begins with the process of star formation. We are made of stardust - and so is all life as we know it, and therefore children of stars. All the chemical elements on earth except hydrogen - including the ones in our bodies - have been processed inside stars, scattered across the universe in great stellar explosions, and recycled to become new stars, planets, and parts of us. Elements are "cooked" by nuclear fusion inside stars. Supernovae are great stellar explosions in which the resulting ash is spread far and wide through the cosmos, forming new generation of stars, planets, and people.
