Wow this is a scary theory.

Earth may be a small target, but it has been traveling in a repetitive pattern for billions of years; in the field of trajectory of billions of astronomical projectiles...what are the odds of a hit?

A big hit like that one? I've heard something like once every 100 million years or so.

Obviously, 1.0 to 1.0.
