Geology by Design: Interpreting Rocks and the Catastrophic Record Book

I first read this book when i was in high school back the the late 80's. I was not certain about my philosophical or theological viewpoints at the time, and I expected to be met with a well thought out argument against Christianity. This is not what I found. Instead, I found the rantings of an angry man who was clearly reacting against Christians and the Church (proper) and wrongly leveling his disgust against Christianity itself. His arguments were weak and ill-formed at best. Needless to say, I was disappointed that Nietzsche could not mount a better attack than he did. I had previously found similar weak arguments (based mostly on emotion) in the text "The Tyranny of God" by Joseph Lewis. Although I am a Christian today, I am reasonably certain that I could develop a stronger argument against Christianity than Nietzsche or Lewis (which I obviously will not do here). So, if you are a Christian looking for a worthy opponent, don't bother looking here. And if you are an atheist looking to strengthen your arguments, I hope you have a better source than Nietzsche.
