You intimated that the Tree of the Knowledge of Good and Evil was unclean. Nothing you have said here dismisses that notion. We were not talking of eating, or experience or Adam's loneliness.In keeping with standard biblical usage of the metaphor of eating to express experiencing something to understand it, Rev 10:8-10, it wasn't the knowing the difference between good and evil that caused any problem as such knowledge was necessary to live with GOD but the eating of that knowledge, the experiencing of that knowledge by ingesting and proving it by the practical method of choosing to sin to see if the warnings were true, ie, to test GOD or to rebel against HIS definitions of the reality of the natural and consequences for sinning.
You may reject that GOD creates evil people by having them to be created sinful in Adam but it is obvious that HE did create a not good in the garden if you accept that Adam was created in the garden because HE tells us straight out HE did it this way:
Genesis 2:18 The LORD God also said, “It is not good for the man to be alone. I will make for him a suitable helper.” Berean Standard Bible
The very good spoken of later was only possible because GOD fixed the not good situation HE had earlier created. Was this not good a part of HIS creation or did Adam introduce it into GOD's plan? I think that Adam's seeking to find his suitable helper among the animals gives us a clue that Adam's being alone and out of step with God was his fault, not GOD's, even before he ate.
Prove the Tree itself was unclean or set aside the silly notion because the scriptures say not to touch anything unclean (2Cor.6:17) that not touching the Tree was an unspoken command in the Garden. Thankyou.
