I found it!

A real live allusion in our modern day world! I was so excited I thought I would share it with you all!

Allusion to the Garden of Eden in “The Nightside of Eden” by HIM

“Divided we stand in the light of a frozen sun
Cursing the gods we have become
We steal the fire from a sacred heart
And bleed the wine unholy
We fall in love with the serpent's song
And fear nothing
In the nightside of Eden
We're born again dead
Forever we are
Forever we've been
Forever we'll be crucified to a dream
In the nightside of Eden
Deranged, we're tearing away the petals of desire
Learning the mathematics of evil by heart
We deceive ourselves to start a war
Within the realm of senses
And descend to the circle number four
Where we are nothing” (HIM).

History of the Garden of Eden:
When god was creating Earth, he created a man named Adam. In order for him to not be lonely, God created a woman named Eve. He created a garden in Eastward Eden and put his creations there. Both Adam and Eve were naked, however they were not ashamed. Then God planted trees and a Tree of Knowledge. He then told Adam that he could eat from any of the trees besides the Tree of Knowledge or else it would lead to his death. Then a serpent came and tempted Eve to take a bite of an apple from the Tree of Knowledge. She then convinced Adam to do the same. After this, Adam and Eve realized they were naked and thus, evil was created. It was also the separation of man from God.

The Garden of Eden in Relation to the Song:
The song clearly talks about the place where God sent Cain (East of Eden). It talks about the evil of the world and is basically describing the opposite of paradise, or hell. When the song talks about descending ‘to the circle number four’, meaning the fourth circle of hell, it means that there is constantly a war between good and evil and in the end, it really doesn’t mean anything. The title reveals the evil that came out of a good place. When you think of Eden, you usually think of a bright place, however, the ‘nightside’ of Eden makes you think of the sin and the temptation that happened in the garden. When the song says ‘we fall in love with the serpent’s song’, it is a direct reference to the serpent that tempted Adam and Eve to eat from the Tree of Knowledge, thus creating evil on Earth. Overall, the song talks about the evil that came out of The Garden of Eden, or more appropriately said in the Nightside of Eden.
