On the sixth day, God created man and realized he was lonely
So, when man was sleeping, he took on of his ribs and created a partner for him. Adam called her woman.
One day, Satan in the form of a snake came to the woman and told her to eat the fruit from The Tree of the Knowledge of Good and Evil. God told the man and woman not to eat from this tree, but she disobeyed.
The woman told her husband to eat the fruit and the eyes of both of them were opened. They realized that they were naked. They tried to cover themselves with leaves.
The man and woman tried to hide from God becuase they were ashamed, but God found them and punished them. The woman would feel pain in childbearing and the man would have to work hard labor.
God also punished the snake. He told the snake that he was to crawl on his belly and eat the dust for the rest of his days. Adam named his wife Eve.
How did you know you are naked?
Later, God sent his son as the new Adam. His son, Jesus taught lessons and did miracles all relating to God. Later, he died for our sin but rose again three days later.
