Look at your hand.
Billions of years ago, the materials in your hand were in a star.
And then, that star exploded as it died and sent those materials out into space.
And the space dust collected together and started spinning.
And then it formed the planet you were born on.
And then you were put in charge of those materials as it formed your body.
// inspired by Doctor Who and the chapter I just read for Physical Science about stars.
