Son, daughter of Christ, Jesus tomb and rapture?

all of this controversy about Jesus and Mary M. having kids has gotten me thinking. The bible says that Jesus promised to return before a generation had ped--what if he did? Christians are denouncing the possibility that Christ fathered children by saying he died a virgin and was umed into heaven physically, so what? What if he kept his word to the letter, and , upon his return, married Magdelene and they had kids--the legends of Sarah and Judah have been around for centuries and are not some new idea dreamed up for the DaVinci code and Jesus tomb doentary. Who says they have to be plugged in to the bible stories?
