Reading the Creation book in the mid 90s is what turned me from a completely disinterested, born-in teenager with "spiritually weak," inactive parents to a zealous 17 year old regular pioneer.
I was young, the internet wasn't widely available, but even still I had a hard time buying into the JW religion if belief in a literal Genesis was part of the deal. The Creation book changed that for me. It's an incredibly persuasive read for those who don't have the mental tools necessary to see through the deception. At 15 years of age and without the benefit of the internet, I was thoroughly duped.
I didn't fully realize the scope of the dishonesty until I was fully out of the religion. My exit occurred roughly ten years after first reading the book. What hurt me the most wasn't so much the blatant deception but the fact that the content was repackaged Creation Science nonsense. There really weren't many original thoughts in the book, if any.
All those years I had looked up to the men whom I thought were intelligent enough to create definitive arguments in defense of the Biblical creation narrative when in reality it was simply a work plagiarized from the body of pseudo-science that eventually gave rise to Intelligent Design.
