So....not written by God, written by fallible men.
The Bible isn't a historical treatise.
The high school or college educated person recognizes there are different literary genres: parable, metaphor, hyperbole, poetry, historical narrative, etc.
The archeological data on the ground does not support a historicity of mass destruction and genocide in the archaic period. The most reasonable literary interpretation is that the Hebrew scribes were using hyperbole and literary licence.
Your strict biblical literalism and your repeated claims of mass genocide are not supported by the data on the ground.
By using high school and college level reasoning, and using the tools of literary criticism our teachers were supposed to teach us.
When Jesus said he was the door, he didn't literally mean he had hinges and a door knob.
Using the tools of literary criticism you were supposed to learn in high school and college, you should be able to reasonably ascertain what is parable, what is metaphor, what is hyperbole, what is poetry, what is historical narrative.
