From her website:

This song was inspired when a friend of mine complained to me about a run-in with some Creationists, and asked "what can you say to such people?" The first words that popped out of my mouth were "humans wrote the bible. God wrote the rocks."

From her bio:

Cat Faber is the offspring of a sasquatch and a space alien, which gave her a unique perspective on things like sports and religion (if those can be said to be separate subjects). Her taste in music is likewise unusual, combining a love for the folksong style with an interest in subjects like science and magic. This made her such a natural for filk that it is astonishing she didn't discover it until she was nearly full grown. She sang from babyhood, though her sasquatch parent maintains she was tone-deaf until about the sixth grade. In 1996 she hooked up with Arlene Hills to form the filk duo Echo's Children.
