God had planted two trees in the middle of the Garden of Eden. One tree was called the Tree of Life and the other tree was called the Tree of the Knowledge of Good and Evil.
God told Adam and Eve they could eat the fruit from all the trees but one.
God told Adam and Eve not to eat the fruit from the Tree of the Knowledge of Good and Evil. God told Adam and Eve that if they ate the fruit from the Tree of the Knowledge of Good and Evil, that they would bring death on themselves and all people. Later, God told them that all people would have troubles, sorrows and death because of what they had done.
Satan the Devil made himself to look like a snake. Satan told the woman that if she ate fruit from the Tree of the Knowledge of Good and Evil, she would become like God. The woman listened to the devil, and ate of the tree, then gave some fruit to Adam and he ate it.
