According to some scientists, the earth itself did not exist billions of years ago, but about 4.6 billion years ago, a giant interstellar molecular cloud gravitationally collapsed to form the solar system. Some dwarf planets, moons, asteroids and other bodies that are somewhat smaller in size than the planets. This is how our home on earth was formed, but in the early days of its formation the earth was not as beautiful as it is today, the newly born earth was shown to be made up of magma, a boiling 'ocean' if you will.
