Adam is described as the first flesh.
Some interpret this to mean that prior to Adam there was no death and that the fall introduced death to the entire planet.
This is also an intriguing conundrum.
What happened to the cells of the forbidden fruit that was eaten? did they not die?
Adam also lived for many years outside of the garden of Eden before his eventual death. Did this mean that nothing died in the whole of creation waiting for him to die?
In fact we have Cain killing Able and so that death also preceded the death of Adam...
So perhaps what is implied something a little different to what jumps to mind at first reading.
The fall definitely changed things from the state they were in Eden. But Eden was of limited geographical extent.
What was going on outside of Eden?
What had been going on before Eden?
I'm going to do things a little different this time round and see what your thoughts are before giving my opinions.
I'll give it a day or so for lots of comments so we can have a diversity of opinions.
