What dies is the innocence of Adam and Eve, stemming from the tree of life; natural instinct. After they ate, they became self conscious of being naked. This awareness was not natural, but was connected to their newly learned knowledge of good and evil; naked is now defined as evil. This was a tell to God that they had eaten.
The stress of human adult living had begun, and the age of childhood innocence was over. Now stresses began for all humans; original sin, as they started to judge each other, often by subjective man made laws of good and evil; pronouns and unclean foods, with death often the consequence of violation of the ancient laws.
A toddler will run around naked, being carefree and full of joi de vie. It is funny to watch; age of innocence. As soon as the parents start to feel awkward and start to teach "right and wrong", that naked is not good, the child's free spirit is lost. If nothing had even been said; child was not force to eat of the tree of this knowledge of good and evil, running around naked would go on much longer.
Interestingly, in the first few years of school, the girls, on average, will learn the rules faster than the boys, with many boys not wishing to follow the school laws of good and evil. This difference appears to be connected to the innate nature of females more geared to the structure of law; Eve. The boys are not as structures and need to be pushed a little harder, before they go along; Adam. This difference; brain differences, allow the males to be more innovative; break the rules, and the females become the capacitance of culture; maintain and teach the traditions.
