Eve was the first woman, wife of Adam, and the mother of Cain, Abel and Seth, and other sons and daughters.
 
Eve, was created by God in the Garden of Eden from the rib of Adam, who interpreted this as her being "bone of my bones and flesh of my flesh."
 
And because of this, a man leaves his parents and is "joined to his wife and they shall become one flesh."
 
Eve was persuaded by a serpent to eat fruit from a forbidden tree in the Garden of Eden. Adam later ate some of the fruit, too. Both were then expelled from the Garden of Eden.
 
The story of Eve is found in Genesis, chapters 2 and 3.
 
She must have been beautiful. Could God who had created the world, and found everything very good, have created anything less than the perfect woman, to be the first wife and the first mother in history? From Adam's rib came his helpmate. Woman. Wo-Man (Hebrew ish = man; ishah = woman) or if you will accept an English language pun that makes sense "man with a womb".
 
Unfortunately for all of us, Adam didn't exercise his God-given dominion to command the serpent out of the garden. Thus he failed to guard and keep it. Result? Satan deceived her. She disobeyed God's command (which she hadn't received directly but must have learned from Adam) Then she handed a portion of the forbidden fruit to Adam.
 
Genesis 3:6 - ...she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat. 
 
Adam could have shown who was head of the family and refused to eat the fruit. Thus, he fell from grace. Adam's sin was initiated by Eve. For that, God cursed womankind with pain in childbirth. Graciously however, He promised, in pronouncing judgment on the serpent, that "her seed" the seed of the woman would one day conquer the foul Tempter: God's son, "...made of a woman."
 
Galatians 4:4  But when the fulness of the time was come, God sent forth his Son, made of a woman,
made under the law,
5  To redeem them that were under the law, that we might receive the adoption of sons.
