Yes--I think I pretty much said that above in different words.

My point is that it matters not whether a story is myth, legend, etc, because there is always lesson or truth to be discerned from the passage. In the case of Adam and Eve, there might not have been talking snakes and magic trees, but we did have a first set of parents who, at the very least we are spiritual descendants of and thus inherited their sinful human condition. In other words--a person cannot dismiss the concept of Original Sin based on the "mythological" character of Adam and Eve. If anything, the Adam and Eve story illustrates why Original Sin exists and where it came from using mythological elements. 

Sodom and Gomorrah may or may not be a legend. We cannot dismiss the moral or social justice implications of the passage because the story might be a legend.  

That was my point.
