Religion

All those dead kids and Jezuz was supposedly one of them. Their birth certificates were invalid, which made it impossible for the young messiah to get his cart drivers license. No prom date for Jezuz.

So Jezuz grew up outside the system with no System Identification Number, hes was SIN less.

Jezuz was a popular name at the time and itinerant messiahs and faith healers was just as popular a profession. It was hard for youg Jezuz to stand out from the crowd. Turn water into wine and sure enough there was a Jesus down the street turning water into mayonnaise.
Wine may be cool but it doesn't mean shit when you want a good sandwich.

And to top it all off crucifixion was just as popular as the name Jezuz was. Why if all the pieces of the true cross were turned into crosses there'd be thousands of them.

Of course the raising from the dead part is pretty special, except on Easter of course, cause when Jezuz died the graves gave up their dead and there were zombies everywhere.
How ya gonna notice one messiah when everyones Nana was home for Passover dinner?

So as you can see it is really understandable that there was no contemporary records. Jezuz was like a cool rock band from the 80's that only exists now on bootleg cassettes.
