Who would have thought that the first extraterrestrial message received on Earth verified by the scientific community would come in the form of a book? And who could have imagined, when opening the book in search of answers, that it would be composed only of questions? Questions, questions, and more questions! What is it like to be human? And what is it like to be you? What is the purpose of gender? How do you know what you know? Is Earth a good home? How do you humans get along? Who names the world on Earth? And, on Earth, does 2+2 always equal 4? And much more. This book for intelligent earthlings (of different ages and heights) poses questions about identity, gender, coexistence, social differences, art, and a long etcetera of topics that say so much about humanity and make us stop to think about our way of understanding and inhabiting the world. With a style as intelligent and rigorous as it is fun and playful, Is There Anybody Out There? is a book to awaken curiosity, conversation, reflection, and debate.
