We've all heard the phrase "seeing is believing," but sometimes it's difficult to believe something is real even when you've seen it with your own eyes. That's how archaeologists and historians feel about the amazing things you're about to see in this video. They've looked at them and studied them, but no matter how much they study them, they're still left with the same sense of wonder. We hope that you get a sense of wonder yourself as we tell you their stories.
