Incredible animations reveal how our planet was pounded by asteroids and comets when it was young
Earth formed about 4.5 billion years ago - and it is believed its first billion years were far more dramatic than previously thought
Asteroids and comets repeatedly smashed into the early Earth and covered the planet's surface with molten rock
Asteroids larger than 300 miles wide struck the Earth’s surface, vaporising the Earth’s oceans, and filling the atmosphere with steam.
Oases of water were left that could have supported the evolution of life
