In spite of the prohibition, Eve and Adam disobeyed God through the prodding of Satan, disguised as a serpent. As punishment, God banished them from paradise and they became mortals. They had two sons, Cain and Abel. Cain, being the envious one, killed Abel because God likes Abel more. God cursed Cain. The third son was Seth and they had more children that the Earth was populated. However, the people became decadent and sinful. God decided to wipe out the population of the Earth with the exception of Noah and his family, plus pairs of animals who were to be saved in the ark that was ordered by god. For 40 days and 40 nights, the flood cleansed the Earth. After that, god promised that there won’t be anymore floods and Noah thanked him. Noah’s children filled the Earth again and they, again, became decadent and sinful. They worshipped many gods and idols including the Tower of Babel. God punished them by confusing their languages and scattered them all over the Earth. Then God chose Abraham to start a people that would worship him including instructions to go to Canaan, promising Abraham that he would be leader of the Canaanites. He also told Abraham to circumcise himself and all of his male descendants as a sign of faith.
