Many Christians don't even want to know the truth. They don't want to believe or even hear of anything else than what they have been taught to believe. They don't want to know or even admit that a lot of what they believe to be biblical is not, but is merely historical myth filtered down through eons of time.
An example is there is nothing scriptural to indicate Jesus is the "Lord of Light" or that Satan is Lucifer; this is an ancient Christian myth originating at the time when all other gods were called devils. A real "devil" is a man with twelve disciples, he is the number thirteen, this is one of the reasons why thirteen is considered unlucky.
Jesus also was said to have twelve disciples (a later interpolation which is now a part of our modern bible), but that comparison was only used to make Jesus into a Christian god like Lucifer once was.
Most Christians today have never heard of Christian mythology, the ancient beliefs of Christians long before there was a Jesus. They don't know--except in myth--how Jesus took the place of Lucifer, and Lucifer became a devil. Many Christians don't even know, or refuse to believe that Christianity did not start with Jesus.
This is the reason why Lucifer is sometimes confused with Satan, but historically, they are not the same at all.
