Why are other civilizations ignored in the Bible?

[Mr. Moncrieff]

I think we're chasing down a red herring. The issue isn't that George A Romero-style zombies lurched around; it's that people known to be dead came back to life and interacted with friends and relatives. Why did nobody outside the story write this down? How did that news not make it back to Rome?

They all agreed it was best not to make a fuss as it would obviously have a significant impact on the future generations who needed to simply invest in blind faith otherwise they wouldn't pass God's test.

It was conspiracy by silence.
