Compendium of Humanity's End - J. P. Prag - Bog

Marco Chung is the oldest human in the known universe.
Displaced in time by his job ferrying people and supplies to the extrasolar colonies around the galaxy, Marco finds no semblance of peace or belonging upon his rare returns to an ever-changing Earth. Meanwhile, despite centuries of exploration and settlement, there have been no signs of past or present life anywhere that humans have looked. Whether it is nearby Mars or far away Novissimus, it appears more and more likely that Earth is uniquely filled with life, at least within the Milky Way.
Despite these setbacks, colonization of the stars continues unabated and has even become the epicenter of popular culture. Due to the fanaticism around all things related to the Human Expansion Program, Marco now finds himself an unwitting celebrity in his own right. All he has witnessed is that on these so-called "Earth-like" planets, nature seems to be constantly trying to wipe every living thing off of their surfaces. After participating in so many journeys to the outer reaches and having a hand in helping to implement the occupations of these exoplanets, Marco is starting to wonder: if we are truly alone in the cold emptiness of space, then is life simply a mistake? And if existence was made in error, what should he do about it?
