Some hold that the Earth coalesced from material orbiting the Sun around 4.54 billion years ago. It might have been struck by another planet, called Theia, shortly after it formed, splitting off material that formed the Moon. By 4.43 billion years ago Earth has developed a stable crust.

Still a long way to go!
