Being unable to believe in a theory the author cannot see with her own eyes (evolution of life on our planet is generally regarded as a relatively long process), the author jumps to a conclusion that the story in a book is more likely, on the basis of compulsion. Considering I cannot prove without doubt either creation or evolution, compulsion is the only thing that can lead me to either side of the fence. So really, the mistake is to be compelled to decide one to be true ahead of the other, if, one regards being compelled a mistake.
