Lily and Ben are twins. They like to play with their toys and books. One day, they find a big book in the attic. The book has many pictures and words. The book is about history.
"What is history?" Lily asks Ben.
"History is what happened a long time ago. Like when people lived in castles and wore funny clothes. Or when people flew to the moon and saw stars. History is amazing!" Ben says.
They open the book and see a picture of a dinosaur. The dinosaur is big and green and has sharp teeth.
"Wow, look at this!" Lily says. "This is a dinosaur. It lived before people. It was very strong and loud. But it is not here anymore. It is gone."
"Why is it gone?" Ben asks.
"I don't know. Maybe something bad happened. Maybe a big rock fell from the sky and made a loud boom. Maybe the dinosaur got sick and lay down and did not get up. Maybe it had no friends and was lonely. I feel sad for the dinosaur." Lily says.
"Me too. But maybe the dinosaur had a good life. Maybe it had fun and ate a lot and ran fast. Maybe it had a family and loved them. Maybe it was happy. I hope it was happy." Ben says.
They hug each other and turn the page. They see more pictures of history. They see people and animals and places and things. They learn and wonder and imagine. They think history is amazing. They are happy.
