Well, that's the reason I asked if they could explain. I don't know why they said no.
I can explain but not in just a few words.
You do not have to be Palagian to say “No”.
Jack RD does a good job showing it was death past down and we all sin, but does not address babies who died and did not sin.
There is a ton of good stuff to learn from the Adam and Eve story and sin is just a small part of it, but to understand sin, you might have to understand everything else.
Adam and Eve were made “very good”, but that is not perfect like Christ is perfect, mainly because clones of Christ cannot be “made”, you just cannot make something that has always existed. “Very good” would be than “as good as it can be made”, so what was Adam and Eve (and all of us) lacking to truly become like God/Christ?
If we can obtain here on earth what we lack there is reason for us being here and what we lack might not be possible to obtain anywhere else, so everything goes back to man’s objective.
Unfortunately, sin has purpose and appears to be needed for all mature adults to help those who are willing to fulfill their earthly objective. The objective drives everything.
Starting with God is Love (the epitome of Love), which means God is totally unselfish and is not doing stuff for His own sake, but is doing everything for the sake of man which is also God’s desire and might be referred to as His sake.
God would be doing or allowing everything to help humans who are just willing to accept His help to fulfill their earthly objective.
So God allows evil to happen to help humans, but God also allowed Christ to go to the cross the help humans.
There is really nothing you (a created being) can “do” to help the Creator, but you can allow of your own free will God to help you, which is God’s desire since God is a huge giver of gifts.
Man’s objective is found in the God given Mission statement of: Loving God (and secondly Loving others) with all your heart, soul, mind and energy. In order to fulfill that mission man must first obtain Godly type Love which will make man like God Himself in that man will Love like God Loves. Would becoming like God Himself not be the greatest gift we could get?
The objective is not to never ever sin, but to obtain this Godly type Love is the first of man’s objective.
There are just something even an all-powerful Creator cannot do (there are things impossible to do), the big inability for us is to be created with instinctive (programmed) Godly type Love, since Godly type Love is not instinctive. Godly type love has to be the result of a free will decision by the being, to make it the person’s Love apart from God. In other words: If the Love was in a human from the human’s creation it would be a robotic type love and not a Godly type Love. Also if God “forces” this Love on a person (Kind a like a shotgun wedding with God holding the shotgun) it would not be “loving” on God’s part and the love forced on the person would not be Godly type love. This Love has to be the result of a free will moral choice with real likely alternatives (for humans those alternatives include the perceived pleasures of sin for a season.)
This Love is way beyond anything humans could develop, obtain, learn, earn, pay back or ever deserve, so it must be the result of a gift that is accepted or rejected (a free will choice).
This “Love” is much more than just an emotional feeling; it is God Himself (God is Love). If you see this Love you see God.
All mature adults do stuff that hurts others (this is called sin) these transgressions weigh on them burden them to the point the individual seeks relief (at least early on before they allow their hearts to be hardened). Lots of “alternatives” can be tried for relief, but the only true relief comes from God with forgiveness (this forgiveness is pure charity [grace/mercy/Love]). The correct humble acceptance of this Forgiveness (Charity) automatically will result in Love (we are taught by Jesus (Luke 7: 36-50) and our own experience “…he that is forgiven much will Love much…”). Sin is thus made hugely significant, so there will be an unbelievable huge debt to be forgiven of and thus result in an unbelievable huge “Love” (Godly type Love).
In order to be forgiven of sin you must first sin, so sin is necessary but not desired.
This messed up world is actually the very best place for willing mature adult individuals to see, receive, give, experience, accept and know Godly type Love. All these tragedies provide opportunities for Love, but that does not mean we go around causing opportunities, since we are to be ceasing these opportunities (there are plenty of opportunities) to show/experience Love.
You do not have to believe the Adam and Eve story is true to get lots of good messages from it. Most people go through a time in which they ask: “How could a Loving God allow such a thing”, which means “why does God not start us all out in a Garden type situation without, needy people, limited resources, death, and questions about His existence?”
What we can do is thank Adam and Eve for showing us and them that what we might consider the ideal situation is a lousy situation for man to fulfill his earthly objective. Adam and Eve as our very best all human representatives did not fulfill the objective while sinless in the Garden and really could not. The situation after sinning outside the Garden did provide a way to fulfill the objective.
That is an introduction to think about.
