Bible Question: What was the First Sin?

It amazes me how the bible is still taken so literally. Seen any talking serpents lately? I don't dismiss the bible as an authority on life but the interpretations are bordering on ridiculous.
The bible taken as a whole is representative of the human race today (and every day) in our history. The good experiences, the bad experiences and everything inbetween.
The mythical stories represent our inner worlds and the physical stories represent the manifestations of our inner worlds. Have you heard that we actually do manifest from thoughts, beliefs and emotions? Maybe this is the real message the bible tells us. We are all responsible and all contribute to the whole experience of life?
It is time the bible wore a modern dress and this concept is far better than anything else I have heard. Time for change?

What kind of creator would set his\her creations up to commit sins? The perception of the meaning of sin is so outdated. The perception of the biblical god is also outdated, and patriachal.
I read these texts as completely spiritual (inner growth). The story of Adam and Eve eating from the tree of knowledge simply signifies the beginning of life as we know it through choice. The serpent, the devil and whoever else was involved simply represent inner thoughts and beliefs. It was never about wrong-doing.

Do you mean the story of Adam, Eve, god and the serpent is a myth?
Also, do you mean the devil wasn't in this part of the story or there is or was no devil, period?Looking at the story from the perception that Adam (masculine force) was tempted to commit a sin by Eve (feminine force) who was tempted by the serpent (negative force), and that it was all created by a loving god (positive force),it just does not make any sense whatsoever. There was never a 'sin' committed.
There are far more logical explanations that don't need rocket science to understand the guidance the bible offers. It is us who complicate it and aren't humble enough to accept a more simple definition.

I used to believe in a literal interpretation of the bible and as I child I believed I was a sinner. I believed I had committed the unforgivable. To me the sin was so great that I would pay for it the rest of my days and I did. I kept on sinning and I could not help it. We all do. I was trying to be good but my children were also being punished because of my sins. All this was internalized from a childhood perspective of bible teachings.
This was all so hard to bear that after many years of guilt and failure, I could do no more. I attempted suicide.
The moral of my story is that had I known my sins were no more than mistakes that we learn and grow from, I could have and would have been so much happier, and now it is too late.

Do you mean repentence after committing a sin that you didn't know was a sin until after the fact?
