The Winter Solstice had passed and the days were getting longer. Adam noticed he could spend more time work in the fields without the light dying. One day, his eldest son joined him. Cain loved his father and would spend as much time as he could with him. He watched as Adam tilled the ground. He learnt the techniques and how to use tools to bring forth the fruits of the Earth.
Great read.
Bible's version is better written (less prolix but more informative).
The implied chronologies of the two excerpts I've read have nothing to do with the historical record. (We call that Genesis 1 - 5.)
I won't be back.
