jan 1, 1000000000 BC - Theia collides with Earth
Description:
(4.5 Billion Years Ago)"It was billions of years ago, when our planet was still mostly fire and rock, when a Mars-sized planet that had been drifting through our Solar System collided directly with the Earth. The impact was so powerful and so violent that the rogue planet was blown into countless pieces of debris. This debris was collected to form our Moon. Many pieces of this unknown planet remain inside the Earth to this day..."
