A parent would reach for this book when their child begins asking big questions about time, history, or their own place in a world that seems to have existed forever. It is the perfect tool for calming the anxiety that can sometimes accompany the realization of how large and old the universe is, turning that intimidation into a sense of awe and discovery. The book uses the life of a giant tortoise as a relatable anchor, gradually zooming out to encompass ancient trees, the pyramids, and the prehistoric eras of our planet. While the book is primarily educational, its emotional core is centered on curiosity and perspective. Robert E. Wells excels at making staggering numbers and geologic time scales feel manageable and fascinating for children aged 6 to 10. By the end, children feel like part of a grand, ongoing story rather than just a small speck in time. It is an excellent choice for kids who love facts and want to understand the deep history of the world around them.
The book is entirely secular and scientific. It mentions prehistoric eras and the extinction of dinosaurs, but the approach is objective and non-threatening. There is no mention of human death, only the passing of vast amounts of time.

This book can be read cold. Parents may want to be ready to explain that 150 years is a very long time for an animal, as some children might find the concept of an animal outliving them a bit surprising. A child asking: 'How long has the Earth been here?' or 'Will I be here as long as a tortoise?' or 'Who built the oldest thing in the world?'
A 6-year-old will marvel at the illustrations of the animals and the size of the meteor crater. A 10-year-old will engage more deeply with the mathematical concepts and the chronological order of the timeline at the end.
Unlike many history or science books that jump straight to the Big Bang, Wells uses a 'comparative stepping stone' method. By starting with a living animal and moving outward, he keeps the scale grounded and comprehensible for young minds.
The book begins with the life span of a giant tortoise (roughly 150 years) and uses it as a measuring stick to explore older entities. It moves through biological time (Sequoias), human history (Pyramids), geological time (Grand Canyon and Meteor Crater), and finally evolutionary time (dinosaurs and early life), ending with a timeline that contextualizes these eras.
