The problem is that both groups still believe in an omnibenevolent God who willingly killed 70,000 children, mothers and fathers just because some stupid king took a census. And they still believe in talking snakes, talking donkeys, and a man named Noah that was able to fit 40,000,000 different species of animals in an ark that was about 1.5 million cubic feet.
This. They also believe this omnibenevolent God killed innocent children just to make an example of some Egyptians and don't seem to see anything wrong with it.
