SATAN is in OT God's 'helper' -he is not enemy of God, he is = literally mean "adversary" in Greek and Hebrew....he tested people, and he
accused them on to God, on his demand.
So, Satan was no evil. It is not authentic to OT - it is just a Christian 'fabrication'.
Same happened with LUCIFER. It is just a mistake of S. Jerome , when he was translating Vulgate Bible in 4 century.
"Lucifer makes his appearance in the fourteenth chapter of the Old Testament book of Isaiah, at the twelfth verse, and nowhere else: "How art thou
fallen from heaven, O Lucifer, son of the morning! How art thou cut down to the ground, which didst weaken the nations!"
In Roman astronomy, Lucifer was the name given to the morning star (the star we now know by another Roman name, Venus). The morning star appears in
the heavens just before dawn, heralding the rising sun. The name derives from the Latin term lucem ferre, bringer, or bearer, of light." In the
Hebrew text the expression used to describe the Babylonian king before his death is Helal, son of Shahar, which can best be translated as "Day star,
son of the Dawn."

Meaning this:
“King of Babylon, bright morning star, you have fallen from heaven! In the past you conquered nations, but now you have been thrown to the
ground”
Lucifer is originally Venus, Heylel (hebrew: 'star of morning') Morning Star...Isaiah 14:12 - fallen Babylonian king Nabukodonosor...nothing
more.
Same goes to story about 'fallen angels' - Nefilem - they are not in the Bible (OT or NT) it is in a Book of Enoch which is pseudepigraphal work,
attributed to to Enoch, the great-grandfather of Noah. It is only wholly extant only in the Ethiopic language and their Bible.

So , all I can se here - is for example copy/past story of Great Flood...just to mention this one.
