Eve and childbirth
You completely missed the point. Sorry for your faulty education. When Adam was created he did not know God. Elohim - 'God separated from man by ignorance."
He wanted Adam to know that he was completely different. This is called 'Holy'. His name Yahweh means ' his thoughts and words/ways are not understood'.
He gave Adam the tree and set it apart as a visual aid of his holiness. I am sure you know what symbols are.
He named it the "tree of the opinion of good and evil". I am sure you have been told otherwise by people who do not want you to know God. The symbol said, "Adam, I declare good and evil, we don't need your opinion on it."
Eve chose to violate that. She declared her own rules by instinct; like an animal. Adam chose to violate it by his willing choice.
God forgave them. He gave them a garment of skin 'owr' that sounds like light and represents his holiness. Their holiness was a bit different. It was a gift.
The 'curse' was not a curse at all. It was a gift. It was Lesson 2 in holiness. God's do not suffer. Adam and Eve both would suffer to remind them that they are not gods. All suffering is the consequence of us, making our own rules and tormenting all around us. Sometimes we cannot identify the source.
He gave them Lesson 3. He separated them more from God by sending them out of the garden. "The man has become believing himself to declare good and evil".
All of this was to address the core problem in the relationship; if we think we are gods we cannot have fellowship with the Only True God.
Sin did not come into the world by Eve, but by Adam. She was deceived by the flesh, just like you when you think you can judge God for the way he runs his universe, or make your own rules.
I know this is new to you and you will want to rant about it too. When you realize that you are not in control, perhaps you will turn to the one who is.
