Is Satan True or False?

Is Satan True or False? If we believe that God exists, we must believe that Satan exists. The Bible clearly states that Satan Lucifer was an important angel before God. When Lucifer thought that Lucifer's throne should be above the throne of God, pride rose in his heart and God removed Lucifer from the position he had placed. If light spreads over the earth during the day, darkness will spread darkness over night. When God spreads light, Lucifer, Satan, spreads darkness over the earth. When God sends to the earth the fruit of the Spirit - love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, and self-control. The fruits of Satan 's flesh: adultery, uncleanness, lust, idolatry, witchcraft, hatred, strife, jealousy, and wrath etc. If darkness covers the earth when darkness falls, evil deeds will increase on earth when Satan rules the earth.
