It's frustrating in the event that it is actually all true and we must believe even if the Bible is all there is-------Unsure
Before you become frustrated have you thoroughly, unequivocally proven to yourself beyond the shadow of a doubt that the Bible is true, that it is the inspired word of God?
However, to be saved from Adamic Sin and have a hope for eternal life, I have to believe in the Deity of Jesus. Hardly seems fair. Very depressing and frustrating.-----------Unsure
Would you be worried about belief in Jesus if there was no such thing as eternal life?
Would you be worried about Adamic sin if you knew that the story of Adam, Eve and the snake is derived from ancient Sumerian and Babylonian mythology?
The Hebrews borrowed, adapted, reworked, reinterpreted, reformatted the "Enuma Elish" Mesopotamian myth to create their own Adam & Eve creation story. Similar stories were current among the Greeks, the Egyptians, and the Persians. The Hindoos had a "tree of life," which was said to be guarded by spirits, and contained a juice that was thought to impart immortality to those who partook of it.
According to Genesis 3:17-19 only Adam and Eve were cursed. There is no mention in Genesis or in the other books of the OT of an extension of the curse to Adam and Eve's children and later descendants . There is also no mention of "the Fall" in the remaining chapters of Genesis or in the other books of the OT. So the early Jews did not interpret the Adam and Eve story as something with universal implication. The story was understood either as allegory or an ancient tragedy.
