In the planetarium, we learned that if you look between the stars, where there is only black night sky, and you look at that space through our most advanced telescope, you don't just see black nothingness. What you see are hundreds of millions of other galaxies out there (source here). Hundreds of millions. And these galaxies are billions of light years away. And our universe is 13.75 billion years old (source here), older than anything I can conceive.
Here I was just one living thing in the vastness of existence, in Oklahoma, making block towers.
