This is one of the mind boggling questions to ever find an answer to. Will we ever know if Adam and Eve were set up or were they at risk of free will? As I tried to understand the text and dialect of the Book of Genesis over and over again, why did God make sinning in the Garden so accessible to Adam and Eve? Why were there trees in that garden that could affect mankind for countless generations? Why use trees at all? Since the Tree of Life was not forbidden, couldn't they have already eaten from it before eating from the Tree of the Knowledge of Good and Evil? The number two is mentioned also reminded me of a scripture in: Matt. 7: 13-14, the two "ways" or "paths" of life. The wide gate and the narrow gate. 13 Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it. 14 but small is the gate and narrow the road that leads to life and only a few find it. .
We have a choice just as Adam and Eve did. The wide gate will be more appealing to some just as the Tree of Knowledge of Good and Evil was portrayed to look at Eve. Satan will deceive many into choosing to enter in through the wide gate. In a way, by God placing the two trees in the garden, it was a teaching tool for all those that followed Adam and Eve. God's plan is always for our good.
How do we know that this isn't the first time Adam and Eve were sinning in the Garden of Eden? Why is this particular story so important to put in all the versions of the bible? There are a lot of questions to be answered in the bible that we search and search for still don't know a factual answer. It seems like God set them up for failure. It was like putting a child in a room with a bowl of candy in it and telling them not to eat it. That puts me in a frame of mind; were Adam and Eve created to be childlike or were they fully mature? I believe that Adam and Eve were created as fully mature adults.
