I have finally figured out why jesus did his zombie routine two thousand years ago rather than in more modern times. Speaking for myself and likely many others; If one of my friends died, was buried and then came back for a visit a few days later, I would've screamed, "AHHHH! IT'S THE ZOMBIE APOCALYPSE!!!!" and bludgeoned him back to death.
In a world where there are detailed zombie survival plans, there's no way the resurrection thing would have worked out.
