Adam and Eve
Chapter three of Genesis says that Adam and Eve had everything they needed in the garden. There was only one thing that God told them that they should not do: eat from the Tree of Knowledge; only from the Tree of Life. The serpent told them that God does not want you both to be as intelligent as he is, so this convinced Eve to disobey God's orders. Once  they ate the forbidden fruit, they were forced to leave Eden. Not only that, but God said that women would experience pain during childbirth, that men would have to work hard to grow food, and that he would return to the dust from which he came at death.
