Simple.
A little planet in a grand and glorious galaxy
in an unimaginable universe.
Our little rock is spinning on its axis,
rotating around our star, the sun,
which is rotating in the galaxy,
which is traveling in the universe,
with other galaxies
and planets and stars.
We've learned so much in the last 50 years!
What will we find in the next 50 years?
Time will tell!
