The Christians thought they would spice things up some and create a holiday along side the pagen one with the good news of the birth of Jesus and add some hope to a dying world.
So you are proud of the fact that they lied about the birth of a mythical creature in order to steal pagan tradition? Wow the amazing mental gymnastics it must take to be a christian.
It seems Jesus IS the reason for the season.
For deluded christians, perhaps. but for the rest of us it has become a matter of tradition. No mystical zombies who require constant praise necessary.
