I didn't; I've always showed my child the non-sense others believe without cause. Now 20, she has a solid grasp on reality and a firm bullshit detector.
Yes it does, it in fact gave two answers to the question.

I don't agree, but if that's what you think, then move along, I don't care.
The juxtaposition of the Santa and Jesus myths has always baffled me. It is truly a spectacular example of the mental hoops people will go to get past their fear of death: even when they are given an opportunity to question their wider beliefs when the truth about the non-existence of Santa is revealed, they are somehow able to effortlessly compartmentalize the "real" unbelievable stories (like rising from the dead, etc) and the "made up" stories (Santa visits all children on Christmas, elves make the toys, etc.) You couldn't make this up if you tried: we piggyback a widely acknowledged fake myth about a man with superpowers on top of a widely believed myth about a man with superpowers, and "grow out" of the former but will go to the grave with the latter. It's the ultimate troll.
Why? There were going to find out anyway.
