I once knew an Iranian woman. She was from the line of high aristocracy and is a limousine liberal in a true sense.
She was always so proud of Persian civilization, which was fine with me. However, she got quite defensive whenever Sumerian civilization was mentioned. In those occasions, she never forgot to insist that all Mesopotamian civilizations were Persian. She was definitely overreaching.
Now I hope that this new findings may make her less defensive.:)
Dr Stephen Oppenheimer, in his book, Eden In The East, makes a compelling case for the refugees from Sundaland being the driving force behind all the Middle East civilisations.
As does Dr Robert Schoch in his book, Voyages Of The Pyramid Builders.
Don't worry, my father claims everything was at one time invited by Iranians.
