This impact of course then helped to create Earth MKII which is now where we live and also formed the moon from all the debris.
Although I stand to be corrected.
This from wikipedia
quote:
In astronomical terms, the impact would have been of moderate velocity. Theia is thought to have struck the Earth at an oblique angle. Theia's iron core sank into the young Earth's core.

You have been corrected.
You can fix ignorance, you can't fix stupid.
