They "Prince and the Pauper"'d God's son's offspring and systematically killed all the witnesses.

If you don't know Prince and the Pauper, they switched them at birth and put human/Satan in Jesus' position, and Jesus in Satan's prison.  With Jesus stuck in prison (hell), Satan ruled and pretended to be earth's savior.  Remember that Satan used to be an angel, and knows how to behave and appear as such.

FYI, the above is partly metaphorical.  I am talking about actual people with genetic lineages to royalty.  There is a bad side of royalty (Satan) and a good side (Jesus was one, Buddha was another).
