They didn't have to. Paganism was rampant all around the Mediterranean hundreds of years before christianity arrived. http://www.britannica.com/EBchecked/topic/244670/Greek-mythology
Point is, how did the Scandinavians and Tibetans find out and adopt christian mythology from their geographically remote locations? 2000 years ago Tibet may as well have been on Mars.
This is Pastor Hamp's fallacious approach to the argument that christianity did not adopt Pagan mythology. The myths are well and truly documented as pre-christian. So, christianity has usurped the stories for its own motives.
