If you read the Bible, there is no way to come to that conclusion. The Bible takes itself incredibly seriously; so to say that
The stories are catchy and have stuck, unwittingly allowing the truth to be carried across the centuries, safely hidden in the minds of men who did not understand it, until the day comes when people grow up enough, to the point where they could crack the shell and eat the fruit.
is to betray just a general lack of understanding of the text. Just because you're exposed to the stories doesn't mean you understand the stories; the truth of the stories; or it's real intended meaning. It takes really smart people a lot of time and a lot of effort to just begin understanding the breadth and depth of the Bible. It's deeply humbling to begin to unravel it and see the story for how it portrays itself. I would really encourage you to take one story from the Bible, for example, the garden of Eden and see how it traces itself throughout the entire scope of the Bible and the different forms and iconography that shows up just from that one story.
