Original sin
The concept of original sin refers generally to the Christian belief in the universal nature of sin. Original sin is considered to be the result of the story of Adam and Eve in The Bible.  In that story (Genesis 3), God only made one rule for them: They must not eat fruit from the tree of knowledge of good and evil. But the snake told Eve, that eating the fruit would make Eve like God. Eve then persuaded Adam to eat the fruit. After they had broken  God's only rule, they were removed from the Garden of Eden.
