✍️ Introduction

“The Book That Saved the Earth” is a humorous science fiction play written by Claire Boiko. It is set in the 25th century and revolves around a group of Martians who come to invade Earth but misunderstand a book of nursery rhymes, believing it to be a powerful weapon. The story blends humor with satire and highlights the role of imagination and miscommunication.

๐Ÿ“– Summary of the Chapter

The story takes place in the 25th century in a Museum of Ancient History on Earth. A historian tells the tale of how the planet was once almost invaded by Martians in the 21st century. The Martians' leader, Think-Tank, plans to attack Earth, considering humans to be an inferior species.

Think-Tank sends a team of Martians to gather intelligence. They land in a library and try to understand human thought by examining books. However, since they do not understand human languages or culture, they misinterpret a book of nursery rhymes—believing it to be secret codes or Earth’s war strategies.

One rhyme about a cow jumping over the moon makes Think-Tank believe that Earthlings have advanced space technology. Another rhyme makes them fear that humans have developed dangerous weapons. Panicked by these "discoveries," Think-Tank orders a retreat and cancels the invasion.

The story ends with humor and irony, showing how a simple children’s book saved Earth from destruction. It also underlines the power of literature and imagination.
