Tribes as you put it MM have always used "stories" good and bad as a teaching tool for their offspring. These stories are regional in nature for the morality (for lack of a better word) of the region,but are global as similar stories are in fact global,generally speaking of course.
Some stories are written,some oral(passed down) but they are basically regional,but global messages of morality. There is one difference all but the "stories" of the Bible(as you see it) are morally inferior to yours. The fact the stories have a similar theme and are probably almost identical in the message,yours are morally superior for some odd reason.
We all have stories about the dangers of jealousy,anger,apathy,love,wild things,evil,dark places and such,they are no different. Theists claim to be morally superior,the only real difference here.
