Why God placed Adam and Eve into the garden of Eden? There was special purpose in God's mind. The garden was intended to be a special place for mankind, before to come on earth. Understanding the purpose is to unveil God's plan for mankind. Into the garden Adam and Eve were instructed by God Himself and they saw many special symbols that would remain in their minds. Tree of life, tree of good and evil, the serpent, the leaves of the fig tree and so forth are not mentioned in the Genesis as a fable, instead if they are totally understood the can enlarge the idea of the eternity in God's plan.
