The Earth formed from the young Sun's accretion disk about 4.5 billion years ago. At first the planet was molten, but the surface of the Earth cooled enough for the crust to solidify about 4.1 billion years ago. Scientists believe that water arrived later in the form of comet impacts, forming the first oceans.
