THE BIRTH OF THE EARTH






Basically after the Big Bang, energy was converted into matter and the Universe was filled with clouds of hydrogen and helium gas. These clouds would coalesce through gravity to form galaxies and stars. One of these stars, our Sun, would form in the Milky Way galaxy. There would be a disk of gas and dust orbiting our Sun, from which Earth would form.
