    The Big Bang

    The Universe is created, creating massive amounts of energy and space dust, eventually settling down into eventually into individual galaxies and nebulae.
  • 4567 BCE

    The Beginning

    Planetary Accretion of the Earth and related planets such Mars begin. Large and small rocks formed from the creation of the Universe begin to collide with each other, forming larger and larger planetary bodies, eventually growing to present-day planets.
  • 4430 BCE

    Asteroid collides with Earth, creates Moon

    A proposed theory is that 4.43 billion years ago, a very large or series of meteorites collide with the Earth with such force, that chunks of the Earth's crust are launched into space, where eventually clump together to form the Moon.
  • 4100 BCE

    Earth's Planetary Cooling

    The crust of the Earth begins to cool down and settle, and terrain began to form.
  • 3800 BCE

    End of Heavy Bombardment to Early Earth

    The event basically consisted of a very large and frequent amount of asteroids hitting the Earth's crust, but eventually slowed to very rare occasions.
  • Period: 1000 BCE to 1500

    Earth's Core forms

    Finally the Earth settles down enough, and the core has a clear definition. The core consists of pressurized iron, crushed under the massive amounts of gravity that the Earth produces.
