You mean, like, the Epic of Gilgamesh? Or like the Egyptian image where it looks like maybe Seth battling a serpent, with Ra looking on? Hmmm . . .
Everyone assumes that the Epic of Gilgamesh was the source story for Noah because it was written down first..but the whole legend is blown up and stylized. The relative simplicity of the Genesis account argues more for it being the original story and the story was preserved by tribes and family traditions that don’t appear to be major Sumerian players. When Abraham’s Father moved from UR to Haran and then Abraham, called by God directly , moved from Haran to Canaan and the environs of present day Israel his tribe/family would have taken those early stories with them including the early genealogies!
Certainly details have been lost but Genesis does depict angelic beings coming down to a race already fallen form God’s grace and interfering with what the Spirit of God was doing with man. ( to coax our race back towards righteousness).(”My Spirit will not always strive with man”) Horrible offspring,lawlessness, violence, and every wicked imagining filling the earth were the results.
Well in the case of “proto Christ arch types”, the Egyptian one is a good example. The myths are much the same... a beloved one of the God’s comes down to help men out, but because of the blindness of men and by evil machinations of demons, the sent one is killed but is resurrected again and evil is vanquished.
The Norse myth of Baldur is a Christ arch type (who is beloved by all the Gods and by men as well) who is killed by Loki’s trickery but is slated to be resurrected again after the battle of the Gods. Upon this resurrection, he will arise to be the new head God and to rule a new race of men. Again, the Christian message is distorted, like looking at the world thru twisted glass but the message is there nevertheless.
