We all know the biblical story from Genesis,where Adam and eve were thrown away from the paradise because they ate from the forbidden fruit,from the tree of knowledge of good and bad.
The author,Moses couldn't explain better than in a story like this the first sin,but now the modern people understand(or should understand) that the tree means much more than a tree,it's a symbol,the first abstractization we remark at ancient people.
We know that the mind of primitive people was as the people,they didn't have any thoughts,because immediately after evolving from monkeys they wouldn't have what to think about.There weren't any concepts of family,feelings,not to mention about any code/rules.
But thinking retrospective,we may assume that man was the weakest being from that jungle(or Garden of Eden as it's wrotten).So a transformation was compulsory in their brains,that was the thing that has changed,they started thinking,how to build weapons,they discovered fire,and they were caught by this virus of domination and they got the idea that harmony was hard to maintain and it would have been better if they had full control.Could this be a sin in god's point of view?Ask god,not me!
Anyway,the holy bible says that Adam and Eve were naked,and they were not ashame.But after the serpent deceived Eve to eat the fruit,and gave also to Adam,they've both become ashamed.Why?If they were the first people on earth,or at least in the earth mentioned by Moses,who could have seen them ?They hid from God among the trees,so the nakedness means that they were pure,without any conditioning.They were innocent people,but they become dirty by knowing that beyond their innocence there is knowledge they couldn't access,yet.So for the first their mind was tricky.They haven't listened to their heart,they became unaware of the beauty of life(who wouldn't feel free in jungle,when you subdue all the nature).In my opinion,the subduing became possesion,this was the originary sin.
God isn't an authority like all the christianity tells us,they weren't unruly in the common sense,but they cheated,life lost the charm after that.
In the modern sense of psychology,they became technique,they were the first people to work hard to live,because they didn't enjoy the company of paradise,they used for the first time left brain,which is said to be scientific,it's mathematical,logic;maybe they didn't know the first thesis of Aristotel or Pythagora's theorem,but they become skilled workers.They lost their faith in something above them,and lost the initial revelation,which grow in the right side of the brain.
So,we can define psychologically that the originar sin was a transfer from the intuitive and connected to God right brain,to the left side,and that had huge consequences over humanity.
There remains infinitely unanswered questions and I've opened also infinitely other questions,which is truly delightful.
