The problem is this: if a God is perfect and omniscient how could it design something that ended up failing?
Now I know you claim the free-will issue. But as we know there are many people who do obey rules. People who follow rules and are obedient have a certain level of understanding and discipline. They can resist temptation and be self-aware and make right decisions. the question is why didn't God create A&E like this? God should have made them adequately resistant to temptation IF it really wanted them to. As we know they were not resistant to temptation (that God put in the Garden to tempt them) and they gave in. Plus, God knew they would give in as it created them.
It was a set up. God designed them to fail. Sin was designed, and Christianity blames A&E even though it was on God. Oddly this didn't work, God decided to flood the planet to cleanse it. But as we know this didn't work as sin returned. So then God decided to impregnate a woman for a son that would then be sacrificed to God so the sins of mankind would be paid for.
Does any of this make any sense for a perfect God? It's a Rube Goldberg theology, but it still doesn't work.
But the Bible's God is NOT ALL powerful because God can Not lie - Titus 1:2; Hebrews 6:18
To make A&E resistant would prove they had No choice.
That would show they had No choice whether to love God or not. They would be automatons, robots.
I find God did Not put Satan in the Garden, but Satan put himself there - James 1:13-15
Each person is drawn out by their own desires.
Eve did Not have to keep on looking at the fruit.
Even a dog, when food is placed in front of the dog when the master says, "No" the dog does Not continue looking at the food but looks at the Master. Eve freely chose Not to look away from the forbidden fruit.
So, to me the 'set up' was put in place by Satan the Devil.
I know of No Christian that directly blames Adam and Eve but blames Satan as Jesus did - John 8:44.
God flooded Earth to save (deliver / rescue) righteous Noah and family.
If God had Not taken the action those violent people would have killed off righteous Noah and family.
That would have meant No one righteous would be left on Earth.
With No one righteous then there would be No one to fulfill the promise of Genesis 3:15.
So, removing the wicked was the only solution so that Messiah could come through righteous Noah.
Yes, of course sin returned but Not everyone became so corrupted as in Noah's day - Genesis 6:11.
Plus, the passing of time was necessary so that we could all be born and think who we would want as Sovereign over us. - Genesis 1:28. This is why there is the gap between Messiah's arrival on Earth and our day.
Jesus explains what conditions would be like before his return - Matthew chap. 24 Luke chap. 21.
Remember: Jesus was Not taking the action of Isaiah 11:3-4 in his day, but much later as per Luke 19:11-15.
