Well, first of all, i'm a christian and we traditionally believe that Jesus was born of a virgin, descended from a heaven, performed miracles, rose from the dead, and ascended back into heaven, from which he will return. greatttt, but...
Personally i think that he was an ordinary man, with high level of morals, anarchist (anti-government), a truth speaker, for that he was tortured and murdered by the government. Mary wasn't a virgin and there is no Santa

BUT if i have to believe in miracles there must be some half real half SC-fictional explanations... 5 BC, a genetically-engineered human-alien hybrid sent to Earth, from another planet (heaven), to fertilize the primitive Human race and awake the hidden powers of mind, the true meaning of life, peace AND love.
Let's say these alien people (angels made of light) have evolved to the point where they can communicate through telepathy, and they can walk on water also
they abducted Mary, and then implanted her with the divine being called Jesus, then they ordered Joseph to protect her !
Greeting from planet Heaven
and Merry Christmas to every one
