What Happened After The BIG Bang?

Nearly thirteen billion years ago the universe formed. But what happened seconds afterwards? Well light formed around half a billion years later. Twelve million years ago, the first stars formed. Li and Fe were made. Nearly eight billion years later, the Solar System formed. Fusion of heavy elements were in supernovas for billions of years. Two billion years after, water forms. Then another billion years, and life on Earth has finally happened.
