This book offers an exciting exploration of how humankind imagined alien civilizations. It presents a broad picture of how people’s views of beings living on other planets evolved—from ancient times up to modern theories of astrobiology. People from different eras—astronomers, scientists, philosophers, poets, and politicians—reflected on possible forms of life beyond Earth and on how an encounter with them might happen.
Anton Pervushin, historian of astronautics and author of popular science literature, a member of the Federation of Cosmonautics of Russia and the Union of Scientists of Saint Petersburg, discusses the following questions: why did ancient philosophers think the cosmos is inhabited; why did Kant believe that the inhabitants of Mars were better than people; how did Herbert Wells instill fear of Martians; could visitors from other worlds have visited Earth in the past; was life brought to Earth from space; how can we detect life on other planets; and when might we become part of a Galactic Community. This book encourages interest in the search for extraterrestrial civilizations and can inspire new researchers in this field.
