“Most of the Israelites did not come from outside Canaan - they emerged from within it. There was no mass Exodus from Egypt…no violent conquest of Canaan. The early Israelites were - irony of ironies - themselves originally Canaanites!
The conquest of Canaan by Joshua could not have happened [as] described in the Bible. Most of the towns…either weren’t inhabited, didn’t exist or were conquered at wildly different times.” —Finkelstein and Silberman
