God gave them paradise or also known as the garden of eden and all things were Adam’s to eat except for the fruit form the tree of knowledge of good an evil.
Then God decides to create a mate for Adam, after trail and error which created animals, but did not satisfy Adam (ok…), he made Eve. Then the previously made snake tempted Eve into eating the fruit… Promising they would become as wise as God himself. Both ate from the fruit and indeed their ignorance was taken away instantly and they felt all things bad, like shame of beeing naked etc. God was furious and gave them some extra punishment by adding pain and hard labour, and made them eat from another tree (the tree of life).
This is the interesting part, they were shun from the garden, having already started their family and Adam and Eve who had eaten from the tree of life would live forever (or according to genesis 930 years). So what else was there outside of the garden? Well they had kids Cain, Abel and Seth. Who are mention in the other genesis books, not being in the garden but just plain old earth a few centuries ago.
Because of the forbidden fruit that was taken all things evil were casted upon all things living, thus interpretations can be made that paradise became Hell…
But then again Hell is never mentioned to Adam or Eve.
In the New Testament, it is described as the place or state of punishment after death or last judgment for those who have rejected Jesus. But Jesus wasn’t around then…
And in general, Hell is a bad place for sinners. Being submitted to pain and hard labour for an almost eternal life is exactly what happened to Adam and Eve.
