zombies are in movies, this is reality,
the Bible warns us,
Matthew 24:37 For just as the days of Noah were, so the presence of the Son of man will be. 38 For as they were in those days before the Flood, eating and drinking, men marrying and women being given in marriage, until the day that Noah entered into the ark, 39 and they took no note until the Flood came and swept them all away, so the presence of the Son of man will be.
people didnt believe Noah either until it started to rain, but it was to late then
