It's an allegory. Just a story to inform the populus that people are inherently sinners, will harm others to benefit themselves and their kith and kin.

It was to settle the theological question are people predisposed to be good or bad. Christianity declared people are predisposed to be bad, to sin.

Or, should I say, my interpretations of the Bibles are that they are historical fiction designed to be a guide to proper behavior. Stories with messages.

Taking them literally and as a whole is nonsense.
