My stages differ from yours, but I get it:
- Still believed in the God of the Bible. I figured "Christendom" had it more right.
- Believed the Bible "could" be God's Word.
- Completed enough study of why Watchtower was a cult and kept studying to see what was up with the root of that religion- The Bible.
- Included Eastern Thought in my studies.
- Similarly to your path, found great books from the likes of Richard Dawkins and Christopher Hitchens and also great videos on the secular establishment of the Bible.
- Finally broke through to see how the Flood could not be true, the god of the Bible was a war-god. Continued to read science and added much about Jesus being a myth or just a man.
- Just as I could never go back to the JW's once the truth about "the truth" was discovered, I could never go back to believing in the god that men created.
My whole philosophy of life was flipped upside down. People come first. While we plan for our futures, we plan for NOW and our IMMEDIATE future, not some hopeful everlasting future. We do our best to enjoy life and family now, before we are gone forever. It is not a dismal outlook.
Understanding "the big bang" and "string theory" are important things, but not knowing all about them doesn't default to "God did it." Humans are in the infant stage of understanding the universe, but religion asks us to stop seeking better answers.
