Waton, how do believe the writers were lying?
Ultimately, this is not about the writers but the facts. The impossible happenings. The Universe is a miracle enough.
These 'miracles' require the overruling of the laws of Nature. A character, that is so mercilessly requiring the slaughter of a victim as a "corresponding ransom" and the death of all descendants over a bite of fruit does not fit , as the author, or proofreader of the bible.
These story tellers were ignorant, trying to create a comfort zone in a scary world.
By contrast, the Joseph story is at least possible, only dreams correctly interpreted. good lessons for monopoly merchandising too.
