The real story of Christmas
How it might have happened-
About 2000 years ago there was this young 13-14 year old girl named Mary. She was engaged to some guy named Joseph who was much older than her, probably in his 40s or so. She either had a secret lover, or she was a little **** who spread her legs for all the local boys, b/c she became pregnant, and had not yet consummated her relationship with Joseph. This put her in a precarious situation, as according to Jewish law, the only future she had to look forward to was being stoned to death as an adulteress/harlot. So, being the typical scheming, conniving woman, and knowing a bit of OT prophecy, she fabricated a story saying that she was pregnant by God, and her child was to be the messiah. She tried to convince Joseph of this, and he either believed her, or more likely went along with her delusion b/c he did not want to loose this fine little piece of *** that he paid a considerable dowry for.
Or most likely what happened-
There was no Jesus, Mary, or Joseph, they were just a made-up legend/fairy tale, like the rest of the bible.
