I been researching information on “Why the The Conquest of Canaan” could not be a real historical account.
I found this on Bart’s blog:
When considering the historicity of the narratives of Joshua, the first thing to re-emphasize is that these are not accounts written by eyewitnesses or by anyone who knew an eyewitness. They were written some 600 years later,
So all the killing of men, women, and children described in the book of Joshua, were false stories that got exaggerated into fictional stories.
The only problem scholars seem to have is-
Where then did Israel come from? Were they already in the land of Canaan? Were they a mixture of the people living in Canaan?
