Do extraterrestrial astronauts visit our Earth in UFOs—flying saucers? Did they do so in the past, and did our ancestors deify them as a result? Did people know what an electric battery was more than two thousand years ago? Who depicted the continent of Antarctica on medieval maps—a landmass that, according to our current understanding, was discovered only 200 years ago? Can some people predict disasters or foresee the future? Do the souls of the dead truly wander through ancient castles? Are there giant creatures in the ocean depths—such as massive squids—that have yet to be encountered by biologists? You can find the answers to these and other similar questions in this book.
