Here's why:
* No futuristic technology: The story relies on existing technologies of the 19th century, like steamboats, trains, and hot air balloons. There are no fantastical inventions or advanced technology.
* Real world setting: The story takes place in the real world, with real locations and historical events.
* Focus on adventure and travel: The central theme is a thrilling journey around the world, facing various obstacles and cultures. The focus is on human ingenuity, resourcefulness, and exploration, not on futuristic concepts.
While the journey's speed was considered incredible for the time, it was based on real possibilities, making the story adventure fiction, not science fiction. It's more closely aligned with genres like:
* Adventure Fiction: Focuses on exciting and challenging journeys, often with elements of danger and suspense.
* Travel Literature: Captures the experience of exploring different cultures and landscapes.
* Historical Fiction: Set in a specific historical period, often with real events and characters.
While "Around the World in 80 Days" is a classic and captivating story, it doesn't fit the criteria of science fiction.
