It all started when god created the universe. He created a planet named Earth, and decided to create life on this planet.
God created a male human named Adam, but realised Adam was lonely and created a female human named Eve. God allowed them to take care and live in the garden of Eden but had one rule for them, they were not allowed to eat from the knowledge tree. One day Eve was wandering around near the knowledge tree and she saw a serpent, the serpent said that she should eat from the tree because her eyes will open to the world around her and will be able to see the way god does. Eve looked at the fruit on the knowledge tree and took some and ate it.
Eve gave an apple from the knowledge tree to Adam and he ate it too. God was not happy about this, he decided to do something about it.
God cursed Adam, Eve and the serpent. To the serpent he cursed him to always crawl on his belly, he will always be above the livestock, to eat dust forever and to be at war with the women and her offspring. He cursed Eve to have a lot of pain during birth of her children and her husband will always rule over her. He made Adam work hard for what he wants and needs. God banished Adam from the garden of Eden.
