    End of Heavy Bombardment

    During this time, asteroids and failed planets began to stop falling down and hitting the earth.

    Core formation

    The current understanding is that the inner core was formed around 1.5 billion years ago, and will continue to exist for more than a billion years. However, it is not proven that the inner core exists, and most of the "facts" are theories yet to be proven.
