He is called the Universal Father, the Source, the Creator of all. And yes, He does exist. That's what got Lucifer into trouble because he doubted the existence of the Universal Father. In his mind, he started asking questions such as why are we here,and what are we all striving to accomplish, where does this long, long, long journey lead to?

In the end, he wanted to be his own person, and when the rebellion occurred, over 500 planets fell, ours being one of them.

Oh and btw, Satan and Lucifer are 2 different beings. Satan was his second in command, Ole Lu had to talk to him for many months to finally get Satan to turn towards the dark side,as it were,and when he finally did , he joined in the starting the rebellion as well.

The Planetary Prince Caligastia, who everyone thinks is the Devil or Lucifer, is actually the one who joined in the rebellion here and helped to bring about this planet's fall.

Satan and Lucifer do not reside on this planet,not since the time of Christ when he walked out into the desert and was tempted.
People want to believe in the devil. There is no devil with horns and a tail. That's a fairy tale made up to scare people out of their money in order to earn a place in heaven.
