- So when you hold this, this rock is four and a half billion years old.
It's a half a billion years older than any rock on earth.

Hey, - Smart people.

Rocks of all, because they hold answers to some huge questions.
How our solar system formed, how earth got the first ingredients for life, maybe even where to find the resources that'll one day let humans travel beyond earth.
