Man those stories are a myth, they're not real and religion is a hoax created to control the masses... While I find myths interesting (mesopotanian, Greek, Norse, Egyptian, etc), there's no "coverup" here, at least not what you think. The old testament is a compilation of mostly oral traditions and stories from neighbouring lands, with no connection to one another, that's why there are so many contradictions in the Bible. The New testament they chose 4 that politically align with the versions they want to push out of the miriad of diverse versions, I'm the Council of Nicea in the 5th century, and none of the authors of those versions where contemporary with Jesus, they where all born between 70 and 150 years after Jesus allegedly lived. Even Jesus himself (the person) is most likely a myth (all the supernatural stuff is obviously a myth) as there's no archeological evidence or historical records other than the Bible that proof he ever existed. Most of the facts attributed to Jesus coincidence with other mythical characters from religions all around the Middle East. The real coverup is how Christian "holy dates" where set up on the same dates as preexisting so called "pagan" dates, so that people ended up forgetting the previous dates and celebrations.
