If someone died and was resurrected, don't you think that someone would have written about it at the time?

On top of that none of the thousands he fed thought to write anything down either. this guy walked around performing miracles and no one, not one person thought to writethis down. i have seen many say,"well in history there is usally a big gap odn't you know it took x number of years to write the story of x. This is not some historical figure, he is performing miracles, making food appear, healing the sick and blind, walking on water, ressurecting people...and not one single contemporary mention.
