In regards to your comment on the discussions of Adam and Eve and miracles in the book, there are a number of them throughout the book. Without giving too much away (it is well worth the purchase), a YEC mom, who visits the class, presents the genealogy of Adam to Noah. This then triggers a conversation between Sam and Uncle Jack (the scientist) concerning Adam and common.
As for the conversation about miracles, Sam asks his uncle about Jesus walking on water and Moses parting the Red Sea. Jack gives his response as a scientist and a Christian. He concludes that he believes in miracles and that they always have a special meaning–though they are the exception to the rule.
I would really recommend buying the book. It is filled with great conversation starters and has encouraged in our family more in-depth study into the topics brought up by the authors.
