Two objects lying in a field; a plowshare and a sword. “Which of these gifts will they select?” pondered Mazda the Lord. Two brothers, sons of Adam both, were passing by that way. They spied the glittering artifacts that waited in the clay. Hevel saw the plowshare would be great for planting seed in sod. Qayin, the sword blade in his hand, looked at his brother odd. Hevel was a Sheppard who minded Rams and Ewes. Qayin grew crops and farmed the land, the only life he knew. For Hevel to possess that gift did not sit well with Qayin In a jealous rage he used the sword and thus Hevel was slain. Qayin could not face his mother’s eyes, with shame he bore his sin. Of his free will he’d swung the blade that did his brother in. Qayin buried Hevel in that field to keep wild dogs away. Then with both glittering gifts in hand, Qayin wandered far away. In time Man would perfect the objects first found in that field. The weapon would proliferate, evolve from Bronze to steel. The tears of Mother Eve still flow throughout recorded time because we are the sons of Qayin and profit from his crime.
A retelling of the story of Cain( Qayin) and Abel ( Hevel) Ahura Mazda in the religion of Zoroaster , is all good but not omniscient or omnipotent
