Can anyone recommend me books that explore the existential crisis that comes with the knowledge of the vastness of space and of our own insignificance? No Carl Sagan or Neil DeGrasse Tyson shit, for Christ's sake.

Any books that explores the existential crisis that accompanies the fact that we are completely irrelevant compared to the vastness of the universe, like a single grain of sand in a beach, upon which we human microbes inhabit its surface?

if anyone recommends Carl Sagan I swear I’ll tell him to kill himself
