"Spoiler: Scientists haven't discovered life beyond Earth, not even a single teeny-tiny organism. But there's a whole lot of outer space, and humans have searched only a fraction of a fraction of it. So do you believe in the possibility of life out there? Or do you think Earth is perfectly unique in its ability to grow organisms? Where Are the Aliens? takes readers on a journey of theories and discoveries, from the big bang and primordial soup, to how the ancient Greeks considered the cosmos, to the technology used today to listen and (possibly!) communicate with far-off exoplanets. Packed with playful illustrations and fascinating factoids, this is the perfect book for anyone who has ever looked up and asked, "What's out there?"--Amazon.com.
