No man has the autonomy to knowledge or spiritual things and i also believe revelation to the things of the Spirit are given hence which makes it progressive. Here is a question from the meditations of my heart: Was the garden of eden suppose to be the ideal for mankind? Lets learn from different perspective.

Question should be; Did garden of Eden ever existed?

You are enough evidence to that so the question wasnt necessary anymore

Recall that God planted that garden and put man there to cultivate it. That garden of Eden was more like a model of how God wanted the whole earth to be. So as,Adam and Eve procreate and mankind multiplied they would transform other parts of the earth to be like that beautiful garden that God had planted and put Adam and Eve in, so indeed that was the way God wanted the whole earth to be, a beautiful garden. The paradise is not lost forever as God plans to restore it under the ridership of his kingdom by his son Jesus Christ.

It was The Light of God, waiting to be developed into a Good Habitation for Mankind.
God has since perfected the Garden's development in Jesus Christ that those who believe in Him will go back to the Garden and remain there forever.
