Adam is created and is given dominion - "rule over".
Eve is made from one of his ribs to accompany him.
Eve is tempted by the devil to eat from the Tree of the Knowledge of Good and Evil.
Eve eats the fruit and gives some to Adam
Adam and Eve have fallen from grace with God and are disgraced by going against his rules. They are exiled from the garden.
Their disobedience brought original sin into the world. Most Christians believe that we are descendants of Adam and Eve so everyone has original sin.
Christians believe that original sin is the reason for humanity's sin. Original sin is believed to be washed away through baptism which is why most Catholics baptise their babies.
