What exactly does Christianity have to do with Adam & Eve?
They establish that man's creation was for the purpose of reflecting the image of God to bring Him glory, in a personal, intimate relationship. They reveal man's desire to "be like God", a position only reserved for the Creator. They also establish that man is incapable of restoring that image and relationship on his own, thus he hid as God walked the garden calling his name.
Most excellent question, thank you.
The Lord Jesus Christ died on the Cross for the sins of folks like you and me. This is the fundamental of Christianity and all orthodox Christians believe it.
The Lord Jesus Christ had to die for our sins, but the question comes up - Where did sin come from?
The Apostle Paul sums it up well "Wherefore as by one man sin entered into the world and death by sin; and so death passed upon all men for that all have sinned." Romans 5:12 . So Paul says that One man brought sin upon the whole world and the human race. So who was that Man?
Looking further in Romans 5 we find the answer "Nevertheless death reigned from Adam to Moses, even over them that had not sinned after the similitude of Adam's transgression" Romans 5:14. From this we see that it was ADAMS transgression that brought sin and death upon the world.
If it was Adam, where can we read this and what happened? Well the Bible answers that in Genesis.
"And the LORD God commanded the man, saying, Of every tree of the garden thou mayest freely eat: But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die." Genesis 2:16,17:. Here God commanded Adam, that HE COULD EAT anything from the garden EXCEPT FROM THE TREE OF THE KNOWLEDGE OF GOOD AND EVIL. If he did then the penalty was stated "in the day that thou eatest thereof thou shalt surely die."
What happened? Well the short version is "And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat." Genesis 3:6
Adam and Eve ate the forbidden fruit, and they died Spiritually that Day and according to the Apostle Paul, the effects of that caused Sin and Death upon the WHOLE HUMAN RACE (Romans 5:12).
But Blessed be God who planned a Savior foreshadowed from the beginning in Genesis 3:15 "and I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel." Who is "thee", it is the Enemy who deceived Adam and Eve to eat the fruit. Who is "her seed"? That is Mary's seed (from the Virgins womb) - The Lord Jesus Christ. And what is "bruise his heel"? That is the Lord Jesus Christ's dead on the cross and his resurrection. And what is "bruise thy head"? It is the Enemies demise.

Great question. The answer is Everything.
