Watching this is ... hard to find the words to describe it. It's insane!

It shows us how mind bogglingly vast the universe is and how we're literally nothing compared to it. Paradoxically, it also makes me feel incredibly potent and capable as a human being in that being this small we can know so much!

Your size is to the distance of that distant spiral galaxy (420 Mly - 10e24m) as a neutrino is to you (effective cross section of a 1MeV neutron = 10e-24m: https://en.wikipedia.org/wiki/Orders_of_magnitude_(length))

We only know what we think we know. We could just be grains of sand in someone else's world for all we know.

"Meanwhile the Cosmos is rich beyond measure: the total number of stars in the universe is greater than all the grains of sand on all the beaches of the planet Earth."

Yeah, but there are more atoms than grains of sand. We can still be grains of sand in someone's universe.
