In the beginning of Candide everything was perfect. They lived in a beautiful mansion and had everything they could ever want. They had a lot of money and food and Candide was in love with Cungedonge. it was great. then came the fall. Candide was kicked out of the palace along with everyone else. he was whipped many times and tortured a lot. he had no where to live and no food. His life turned horrible. He had no wehre to go and everyone basically died along the way..except not really because they all cam back to life. BUt his is symbolic to the Garden of Eden because in the beginning Adam and Eve had an amazing life and everything they could ever ask for. They had each other and amazing food but then they ate the forbidden fruit and they fell from there. the committed the one sin that they werent allowed to do. they then went from living in the perfect place to living in the most sinful world.
This is just like how Candide went from living in the perfect place to the most sinful.
