Yeah. It becomes pretty incomprehensible.

Another fun way to frame it: 230 million years ago, it’s the middle of the Triassic and dinosaurs are getting their start.

So, (very roughly) from around the time dinosaurs first appeared until now (with all the evolution and extinction in between that eventually led to today’s animals and humans, including all of human societal and technological development squeezed in at the very end) the solar system has orbited the galaxy one time.

It's also weird to think about how the constellations we see today were identified hundreds (or thousands?) of years ago and the stars' positions in the sky have changed little in that time. Yet one sun-orbital-period ago, it must have looked very different.
