War of the Gods examines ancient scriptures from India, Siberia, Tahiti, and many other regions of the world independently on reports of battles in the stars. Weapons of unimaginable destructive power were used in the battle. Use of one of these weapons destroyed a planet completely.

Traditions from all over the world depict the gruesome effects of the battle in space. Many ancient stories speak of it raining fire from the sky for years. The people of the time tried to protect themselves from this, and thus created more testimonies that prove the star war and contact with beings from other planets.

With impressive examples von Däniken illustrates some of the numerous cities that were dug underground as safe harbors from the destructive boulders. Miles and miles of underground passageways have been discovered around the world as they made space for villages and entire cities.

To end the book, von Däniken presents his newest discoveries of an event that can only be described as shocking: In 2017, the author was informed that strange mummified creatures were found near the Peruvian village of Nazca. They lived several thousand years, had three fingers and three toes, and had exceptionally long heads. One of the mummies, apparently several thousand years ago, had been implanted with a metal plate under the skin. Scientists agree: These creatures are not from Earth!
