Christians did you know lucifer was a Roman god before , Christianity was even created?
There is no Scriptural source which defines Lucifer as Satan. In fact, the word Lucifer was an addition to the Scriptures in place of the Hebrew word, Heylel, which was the literal name of Venus; and, Shahar, which just means "Star of the Morning" or sometimes translated, "Son of the Morning'. The word was in reference to Babylonian Kings and titles they used to claim their divine right to rule. Artifacts such as the Cyrus Cylinder, confirm such assertions were made by kings of the ancient world.
Babylonian Kings such as King Nebuchadrezzar, who according to Babylonian culture, was either worshipped as a God, or an agent or son of God and very common title which they bestowed upon themselves. According to Daniel, Nebuchadrezzar was given all authority and dominion over mankind, beasts of the field and birds of the air, and where they live. God made him ruler over them all with the title of King of Kings a title also reserved for Persian King, Artaxerxes and in Christianity to Jesus Christ. In such way, a man who has dominion over the beasts of the field, birds of the air, and over mankind, indeed had his power based in heaven and were called by the title, Light Bringer, Morning Star, Son of the Morning, etc. and to lose such authority would have him fall to earth.
In all actuality, there is no scriptural source which defines Lucifer as Satan, nor has any description of Satan being an Angel of Light who rebelled against God and was cast out from heaven and changed to the serpent, Satan. The Latin word was added to the Hebrew Text by Jerome in the 4th Century and was in fact the first to ever present the belief that Lucifer was the serpent in the Garden with Adam and Eve. In addition, the reasons for Jeromes misguided and inaccurate translation of Heylel, may be found in his religious politics within the church itself. One of Jeromes main adversaries (satan means adversary) was the Bishop of Cagliari, who was also named Lucifer Calaritanus, who founded the Luciferians. Hoping that the allusion itself was strong enough to condemn the Bishop of Cagliari and his followers as heretics, Jerome hoped to have their ideas and movement abolished. In the 7th Century, Augustine focused on the Vulgate mistranslation and added more to the idea of an angel named Lucifer who rebelled against God because of pride and took down 1/3 of the angels.
