Sodom and Gomorrah

Sodom and Gomorrah were two cities that a long time ago did a lot of bad things. The bad things the people did were so bad that God was mad and He decided to punish them by sending down fire from the sky to burn the cities. So after the fire was gone, there was nothing left of Sodom and Gomorrah. People now use the story of Sodom and Gomorrah to talk about how important it is to be kind and to do things that make God happy.
