Day the Earth Died

The story is about an event that happened a long time ago. It describes the adventures of three children and something mysterious they found in the mountains. They were unaware that it would affect their lives from that time on. Not a lot is known about the people who lived at this time, some of it is fiction though some events are recorded in history. These events shaped our history, and made the nations as they are today. But can we learn anything from this? Or is it just an interesting story for us to ponder on? The reader always has the final say.
