After reading a science text on radiometric dating, I changed my mind about its accuracy. The WTS always had said that radiometric dating was quite flawed (unless it happened to agree with them, like with the shroud of Christ thing).
I knew science has found humans that were older than 6000 years. The only way I could correlate this with my JW understandings was to either say radiometric dating was flawed or the JW understanding of the Bible was flawed. I could no longer do the former so I started doubting that JWs had the complete truth.
I next analyzed the 1985 Evolution book and was floored by the blatant misquotes.
The wall of faith crumbled.
As it stands now I don't even believe in God let alone the Bible.
