::As far as I know, no scholar thinks that the immigrating Israelites, if any, were responsible for the destruction of Jericho. The walls appear to have been brought down during an earthquake which preceded the immigration by several hundred years according to carbon dating. See Timeline_of_Jewish_history#Biblical_period and Chronology_of_the_Bible#Abraham_to_United_Monarchy. If no Joshua at Jericho, where can we start trusting the bible for dates (and facts)? And who exactly is using the bible for history, outside of fundamentalist preachers? It's not that sort of a history. As another editor has noted, it would be like using "The Diary of Anne Frank" as a substitute for "The History of World War II!" They may both be "true", but one cannot be readily substituted for the other for most uses. 
 ::It would be a bit of a reach for anybody in those days to leap from paganism/local deity into worldwide monotheism. Neither did the Israelites. See El_(deity)#Hebrew_Bible, Yahweh, and Asherah#In_Israel_and_Judah. This should not be some local "voting" process, whereby one person decides the number of "scholars" on one side or the other! Particularly with only one person voting!
