Absolutely. If we assume validity for sake of argument, then it becomes clear that very little of the things in the bible could have been figured out by these guys alone. "All Scripture is God-breathed, and is useful for teaching, rebuking," etc. And by "God-breathed," I don't care what you guys say, it means that it was inspired by God. It doesn't mean literal breath. If you assume literal all the time, then no, the bible doesn't make sense. Neither do 90% of all euphemisms, jokes, sayings, etc.
Just a preemptive strike there, lol. And, no, that doesn't make the bible a joke, either. What that means is, these people DID add their own flavor to the text. They used their own types of descriptions, comparisons, words, etc. which were a part of their culture. Just like a rap artist and a housewife are going to add their own flavor to their testimony, so do these people.
