Did I invent Enki? I did not. Enki is a product of the ancient Sumerians, for whom s/he was:
The Sumerian high god of water and intellect, creation, wisdom and medicine who could restore the dead to life. He was the source of all secret and magical knowledge of life and immortality. Enki possessed the secret of me, ‘culture, civilization’, which is the genius of progress in knowledge to lead humanity. He invented civilization for the people and assigned to each his destiny. He created order in the cosmos. He filled the rivers with fish. He invented the plough and the yoke so that farmers could till the earth with oxen. He made the grain grow. He is the father of all plants.
