You have it all wrong. Jesus was a robot, sent back from the year 2442 A.D.
In the 25th century, society had become perfect, there was an end to poverty and hunger. But one mad scientist thought it might be interesting to see what happened if he sent a robot back to the year 4 AD, so as to spread rumours about an almighty being, to see what impact it would have on society.
The impact was disastrous, but not disastrous enough to stop him from sending the robot back. And consequently, the world is going to be destroyed in the year 2443.
