The Humans, by Matt Haig, is both humorous and complex. It is both a tale of aliens, technology and science, as well as a book about what it means to be human, what it means to love, and to be loved. It's a book that points at the contradictions and idiosyncrasies of everyday life, humorously, and without the doom and gloom voice that we've grown accustomed to everyday. It's a book that shows the value of life and love, companionship and the beauty in vulnerability. Overall this is a great book chock full of big ideas and humorous insights on the human anatomy. I highly recommend it.
Regarding humans unfavorably upon arriving on Earth, a reluctant extraterrestrial assumes the identity of a Cambridge mathematician before realizing that there is more to the human race than he suspected.
