If you were ever wondering whether aliens exist, just know it also comes with difficult, scientific analyses, and conversations on what does it mean be human, when we inevitably find out. Luckily, all of that has been condensed into this lovely book and tv series, with quite a few differences to work through, that I've done all the work to dissect. Hopefully after you tune into the episode, you too will never have to answer an alien's phone call. BYYEEE!!!!
