Timeline of the universe's evolution from its initial state as a hot, dense point to the present day, focusing on the formation of atoms. They explain how the Big Bang produced the first simple atoms, primarily hydrogen and helium, and how stars later formed heavier elements through nuclear fusion. These heavier elements were then dispersed into the universe through supernova explosions, ultimately forming planets, stars, and galaxies, and eventually providing the building blocks for life on Earth.
