Lamech, for his part (as contained in the Book of Enoch), said: "I've put in the world to a child, different from the others. It's not like men but it seems a child of messengers from heaven. " This reference suggests that he, like the people of the time, were familiar with the characteristics or peculiarities presented by these "sons of messengers from heaven" and who knew of the particular relationship that is established between humans and these mysterious beings.
In another part of his legacy, Enoch refers to the union of the heavenly bodies with the daughters of men: "And the messengers, the sons of heaven, they said among themselves:" Come on, women choose between the children of men and have children. " Of such unions, the daughters of men "was conceived and put into the big world giants." This story, which is confirmed by other passages in Genesis, has similarities with the traditional narrative of the origins of many other peoples of the planet. In all cases, the men of this cosmic sexual exchanges are of terrestrial origin, while women who give birth to the giants are human, terrestrial contacted.
