I’ve been looking at the symbolism of the Tree of Knowledge of Good and Evil and it is a smaller tree as compared to the Tree of Life and at the top is a woman coming out with either a snake body for her lower half or she is coiled in a snake.
The shape of this tree is almost a T or a Tau. The fact that the serpent is shown as a woman and is often associated with Lilith is very telling. Per my exposure of Jewish Kabbalah-Qlippoth, I have shown that both of these trees are genetic representations of family trees and one corresponds to the Cronides and the other the Prometheans. Lilith is a descendant of Prometheus and is said to have mated with Samael (who is also a Promethean descendant) and both of them are part of the Qlippoth (Tree of Death). Lilith is shown as a red-haired woman with a coiled snake around her and is sometimes confused with Ishtar-Aphrodite who is shown with lions.
I believe the Tree of Knowledge was the symbolic equivalent of the bloodline of Prometheus-Lucifer and that is why the tree was forbidden. Prometheus-Lucifer-Set was a red-haired white man and Lilith is often represented as a red-haired white woman. There is also the possibility that the red-haired woman-snake can also be Prometheus-Lucifer-Set-Satan since he is often represented as a bisexual/hermaphrodite.
