Explain Adam and Eve in the context of Darwin's theory of evolution.
I'll take a stab at it. Adam and Eve is a wonderful allegory that mourns the loss of innocence of human beings when we became truly self-aware. Our primate ancestors were provided for by God, so they lived from day-to-day, foraging for food, making love and not fretting over the Big Questions: Right and Wrong, how to organize a society or what purpose there cam be in a brief, finite existence that will end in our death and our childrens' childrens' childrens' death. But once our cortex evolved, we lost our innocence and became able to question the wisdom of the Universe (i.e., God) and we became responsibnle for our lives and oiur sustenance. Our lust was now, not only a beautiful drive that allowed us to "be fruitful and multiply", but could lead to rape and child abuse. It became a potential source of shame. We became worldly and self-centered, in love with how smart we had become after eating the Apple. We became vain and capable of sin, like lies, theft and murder. So we cast ourselves out of the Paradise of innocence into the harsh world where we would be forced to choose our actions in a minefield of good and evil, with only our limited brains and pleasure-driven natures as guides. The Lord, knowing our weakness, foresaw the misery we had unleashed on ourselves through our foolish pride, when we succumbed to the bad influence of the Serpent appealing to our baser nature and turn our backs on God.
At least this is one interpretation. There are, of course, many more.
Some see it as a metaphor for our transition from simple animals to what we are now: scientists, artists and philosophers. In this version, God is our "natural", animal nature, while the serpent is like Prometheus, giving us our intellect (instead of fire), with which we can cast off our subservient role and become truly human.
When it is a positive force, religion gives us a mythic understanding of our humanity with its trials and joys and gives us some insight into the deeper wisdom about our lives that does not chamge with advances in scientific knowledge or technology.
