As for making graven images of things in or beneath the earth--How would we know what those things looked like to make images of them if they are beneath the earth, assuming that's to be taken literally?
IN heaven above or IN the earth beneath or IN the waters under the Earth = implied bases or cities.
Do you know what the Golden Calf represented in the Exodus?
Taurus, in the Pleiades Constellation.
Exodus 20:5 Hebrew Text Analysis
Satan and his angels live here. They've always been here, LONG before Adam and Eve were created. Satan and his angels worship the creation (like our physicists; God Particle). They do not worship the creator. So where is Satan and his angels right now? What parts of the Earth do they reside? Since you believe that Eden no longer exists, where on the surface of the Earth do they all live now?
Angels have bodies but can also exist in higher dimensions. When an angel's body is in a higher dimension, they appear from the perspective of lower dimensions as light (ghost or immaterial). Some angels look human while others do not. But they all share one thing in common, they're all telepathic and can hear your thoughts as well as speak to you either through verbal or telepathic communication.
Bible tells you this and it's why when you pray that you address God directly and NOT angels, or Mary, or Saints, etc. An angel will hear your prayer and deliver it to God and if you're worthy of a response, one will be granted and delivered by an angel.
There are good angels and there are bad angels.

Genesis 19:1 Hebrew Text Analysis
Or how about Ezekiel?
Ezekiel 40:2 Hebrew Text Analysis
What about Enoch or Elijah or Moses?
What about Satan tempting Jesus?
Sons of God? How does that relate? I believe in the angelic realm.
Define angelic realm.
I believe the Garden of Eden existed.
If past tense and the Garden no longer exists, what happened to it?
Where was the Garden of Eden and where did the Serpent in the Garden and guardian Cherubs go?
Where are the Sons of God now?
We know what happened to their offspring, but we also know that some of the Nephilim survived the Flood.
Genesis 6:4 Hebrew Text Analysis
So where did they go? Unless you think that they held their breath under water for 40 days and nights and only a handful survived?
FYI...the Nephilim had 6 fingers and 6 toes.
