asteroid huge in earth's history

This ancient asteroid allegedly created the Earth's crustal tectonic plates, 3.5 billion years ago!

That looks to have been the largest since Theia...

Here's an interesting alternative to the Theia collision:

In it, two large bodies collided, and the leftover debris became the Moon!

Interesting theory Varek. The theory would explain the reason why there is not an atmosphere on the Moon given the fact if the Moon came from a collision with Earth then there should have been enough spin to keep the Moons core active an supporting life.
