"Hey,
Do you mind if I tell you a story,
One you might not have heard?
All the elements in your body were forged many,
Many millions of years ago
In the heart of a far away star that exploded and died.
That explosion scattered those elements across the designations of deep space.
After so, so many millions of years,
These elements came together to form new stars and new planets
And on and on it went.
The elements came together and burst apart,
Forming shoes and ships and ceiling wax and cabbages and kings
Until eventually they came together to make you.
You are unique in the universe.
There is only one of you,
And there will never be another.
Getting rid of that existence isn’t a sacrifice,
It is a waste."
-The Doctor
