Moon forms 4500 mya

A Mars-sized body (~10 % of the Earths mass) collides with the Earth. The debris ejected shortly coalesces to form the Moon. The Earth's surface and proto-atmosphere is vaporised and a magma ocean forms encompassing the entire mantle. This event marks the end of Earths main accretion phase. Earth is uninhabitable for at least 200 million years.
