Pagan Origins of the Christ Myth
You already know Christmas trees and Easter eggs were originally Pagan, and you probably know the traditional mid-winter and spring timing of the two holidays was Pagan too. Mildly interesting. Not what you'll find here.
What you'll discover here is that Christianity inherited everything from the Pagans. The core of Christianity -- the worship of a dying Godman who is resurrected, ascends into heaven and brings salvation to mankind -- was also the core of a number of ancient Pagan religions that began in the Near East two thousand years before Jesus.
