A few more points:
Lucifer is another name for the planet Venus, the "morning star".
Jesus did not claim to be God.
Renaissance art depicting the seduction of Eve shows the serpent as being female (hm, I wonder if all that Biblical misogyny had something to do with that). You can see this, for instance, on the Cathedral of Notre Dame.
The verse from Revelations does not say that the serpent being referenced there was the one that tempted Adam and Eve.
This is all, of course, pointless, since it's a religion, and religion is what we call a mythology that sufficiently many people still believe to be true.
