Your first error is lumping together several names....

It's a common mistake.

Might as well lump Jesus in there too.

Jesus claimed he was the bright morning star (Venus) and the Bible says that Lucifer was.

You'll never understand any of this until you get that Lucifer just means enlightenment. It's more commonly referred to as the shining ones , or enlightened ones. Daniel says in the end the wise will SHINE like the STARS of the heavens.

Further drawing the connection between wisdom and shining.

Like we do now days. Do we not draw a light bulb over someone's head to represent intellect or idea?

Jesus also said that we are ALL gods, and that he would be raised up like the serpent in the desert.

Is jesus claiming he is satan?

No. The serpent has always meant whats now called kundalini energy. Remember, Jesus went through several phases.

Normal, rabbi, transfiguration (now called rainbow body), death, resurrection and ascension.

If it all sounds very new agey or buddhist to you... you'd be right.

And if you curious, enjoy the rabbit holes THAT leads to.
