Cain was the name of the Devil’s son. Contrary to his brother Abel, Cain had dark complexion, which stands for evil, which is dark.
While Cain was the child of Lucifer and Eve, Abel was the son of Adam and Eve. Cain murdered Abel, making him the planet’s first murderer. He was envious and jealous in abundance. Another name for the Devil or Satan is Lucifer.
The Abrahamic religions hold that the first woman and man on Earth were Adam and Eve. As a serpent in human form, Lucifer tricked Eve into having a sexual connection with him. She gave birth to Cain and Abel in this manner. A fallen angel, Lucifer’s name translates to “morning star” or “shining one.”
