Eddas would not include the information Sir Laurence has as a result. That is what makes this book very special. I did not interpret Cain as having hatred for Abel from Genesis of the Grail Kings. Indeed it was quite the opposite. Cain has been 'the fall guy' just as Eve has been branded the down fall of Mankind quite unjustly.
History is written by the victors.
It is interesting to re-read The 12th Planet by Sitchin. Although this terrific author did not make the connection to Monotomic Gold, it is easy to see the references to this substance. There are many books available that discount Laurences works both recent and old. Sir Laurence is right when he states during interviews that one must go back to original sources during research.
