One of my favorite concepts to ponder: “are we alone?”
This book dabbles a bit of the science behind this concept and explores the way humans have imagined life outside of earth. Green focuses on science fiction books and movies and the way we may not even be able to imagine lifeforms outside our own human-centric and earthling imaginings. And in fact , don‘t platypuses sound like a made up animal? The issue: we don‘t know how to define life.
