Ok, so educate me on how the genre makes this a historical narrative. Regardless whether the fruit is an edible product that upon consumption caused guilt or is merely guilt generated by being taught the difference of right and wrong, the sacrifices animal or Messianic psychologically relinquishes it, and restores us to the Heavenly Father.
Let's examine what you claim God supposedly revealed to you. Does the Word of God teach that the emotional feeling of guilt keeps us from God so the sacrifices of animals and Jesus eliminated that guilty feeling? No! Here it says people still have the guilty feelings but can have a relationship with God because of faith in Christ:
If they could have provided perfect cleansing, the sacrifices would have stopped, for the worshipers would have been purified once for all time, and their feelings of guilt would have disappeared. let us go right into the presence of God with sincere hearts fully trusting him. For our guilty consciences have been sprinkled with Christ’s blood to make us clean, and our bodies have been washed with pure water.
