The whole Christian idea is basically:
If you are a christian, you believe that:
-a magical wizard who has been living forever created the entire universe just by saying so, all in just one week
-Humans were created by that same magical wizard who has been living forever, because the wizard said some magical words, and a man was created. Then the magical wizard created a rib-woman out of the man, and the rib-woman then did something bad that an evil snake told her to do. Fast forward a couple thousand years later, and we have the magical wizard's motherless son born into earth from a virgin human girl. The wizard's son was so magical on earth that he gathered a lot of followers, and the authorities didn't like him, so they put him on a cross and killed his body. But a couple days later he magically rose up from beyond the grave and then came back for a little bit to show people even more that he was the wizard's son, and to listen to the stuff that the magical wizard no one had ever seen said, and to love him with your life.
Yeah, that sounds TOTALLY legitimate.
