The author, Dr. Susan Wise Bauer, believes that it is the responsibility of the parents and their local faith community to teach children about creation and/or stories of origin.
Within Christianity, denominations and individual adherents teach the Creation Story with various nuanced interpretations. Each family can ask its religious authority for appropriate resources that match the family’s beliefs.
Each world religion tells a story of origin, and families differ in how closely they stick to that teaching. It is better left to each family to use the appropriate resources in ways that support its beliefs.
For this reason, The Story of the World starts with the first nomads.
