Author (All Tomorrows)

The Author is an alien researcher who studied the history of the Human race and its several descendants and authored a book on the subject.

At the end of the book, it's revealed that it is told from the perspective of the author, an alien who is studying the now extinct humans. There is a picture of the author holding a billion years old human skull in a tentacle-like hand attached to the middle of his body.

The author does not know how humanity went extinct, but in his opinion, it's the trip that matters, anyway.
