One Of The First Fantasy Novels

Archaeologists recently unraveled a fantasy novel dated back to 2 A.D. It was written by a Roman who lived in Syria. The novel included many imaginary ideas which were way ahead of that time. There were scenes where humans landed on the moon and found aliens. This Roman went on writing about an interplanetary war and about the discovery of North America. How could he predict things which were not going to happen in any near future? Historians still find this book intriguing.
