You see, i believe in what's called the "New Earth Creationists" Theory. Whereas, she belives in the "Old Earth Creationists" Theory, which states that geology and radiometric dating has shown that the world is billions of years old. She believed that God created the Earth itself, the earth's life forms, and the rest of the universe at that time. So in fact, she believes in the literal interpretation of an inerrant Bible, interpreting the six "day" creation interval as occupying a very long interval of time.
We used to go back and forth all the time, but they really made for some interesting debates.
