God has never created hell. All things those He created were created “good” (Genesis). Nothing bad was present before the fall.
Only when man decided to believe in a lie out of “the fruit of knowledge of good and evil”, only then hell was there.
It was writen that God only created light (the 1st day of Creation), and He “never created darkness”. John chapter one insists that “God is light, and in Him there is no darkness at all”. Darkness in the old testament also mean “the absence” of God’s light, that “the light” also means God’s presence.
Whatever God did not created, does not exist. Thus, darkness does not exist, in other words : God’s absence is nothingness.
Now, man was created for the purpose of “immortality”, but later on, man choose to believe in “nothingness”. Because of man’s choice, “nothingness” becomes “forever nothingness”. The attribute of “forever” comes from man’s immortality.
Now there it is : “hell” exists because of man’s choice.
Hell by definition is the absence of God.
