If Genesis is a metaphor, where did humans acquire original sin?

[Oldiesfreak1854]

The existence of evolution does not have to mean that Genesis is a metaphor, or that original sin (however you interpret it) is a myth.  I personally believe that God created the world, including the original species that populated the Earth, and that they evolved after Adam and Eve's sin introduced death.  Although I don't think everything in the Bible can be interpreted or understood literally, I always interpreted the account of Genesis 3 as being literal because I see no other way for it to work.  And Paul seemed to take it literally, too.

As for original sin, I don't know that I believe in it the way that it's traditionally been understood.  I prefer the Eastern Christian understanding that humanity inherited Adam's weaknesses and fallibilities, but not his guilt.  Denying original sin doesn't require you to deny that we are all sinners; you simply have to accept human fallibility to acknowledge that everyone sins.
