The levels of hell aren't what you think. However, they're what we would expect. The Hebrews had a well developed idea of life after death. For them physical death, the grave, was a portal into a complex underworld realm: sheol.
A major theme of the Bible, particularly the New Testament, is that we have two natures: carnal and spiritual. These two natures are at war within us.
When God said, let light be, the sacrificial lamb was slain from the foundation of the world. That's why it went dark at the end of the first day, the second occurrence of darkness that we have to account for called night.
We're told that the anointed cherub was in Eden the garden of God. He was upon the holy mountain of God and walked up and down in the midst of the stones of fire until iniquity was found in him.
Creation was corrupted before Adam and Eve sinned in the garden of Eden. It was created in a corrupted state in order to manifest free will. We can prove it using a process we call deductive questioning.
God created the universe so that we can sin, otherwise there's no free will, and that means God created a universe in which sin is possible. Sin isn't an accident.
There are two issues that help us to understand the reason for why we were created with free will and how this is even possible given the nature of God as pure and holy, not to mention omnipresent and omniscient.
Jesus crucifixion didn't remove original sin, it gave us a way to be free from the consequences of it.
Original sin is why mankind is in a fallen state. However, that's not our fault. We're born into this system but we're not going to be held accountable for it. We have our own sin which is why we're under the judgment of God.
We're going to straighten out the spaghetti but it can get bogged down in technicalities, which is why having a simple answer is preferable.
