The book that saved the earth …

Martians planned to attack the Earth. The ruler of Mars, Think Tank instructed one of his Martian-Noodle to gather information about Earth. He saw that other three crew members-Captain Omega, Lieutenant Iota and Sergeant Oop found some books in Centerville Public Library. A book named 'Mother Goose' contained nursery rhymes. Omega managed to read some nursery rhymes like 'Mistress Mary', 'Humpty-Dumpty' etc. Think Tank completely misinterpreted the rhymes. He thought that Earthlings were intelligent enough in warfare and had advanced technology to grow high exposures. He was shocked to discover that metals could be grown in fields. On seeing the image of Humpty-Dumpty, he thought its head resembled that of his own. He feared invasion on Mars by the Earthlings. So instead of attacking the Earth, he decided to migrate one hundred million miles away from Mars to Alpha Centauri. Hence, the title 'The Book that Saved the Earth' is apt.
