Option one, although certain people don't know like my granny but I decided for her happiness to be a hypocrite.
I can't ever remember believing in a god but I do remember asking the overly-simple but still unanswered question; Where did god come from? "Oh, he always existed"...It just didn't sit.
I think a failure of the church is the teaching of the bible, teachers would talk as if Noah's Ark, Garden of Eden etc. was true even if they didn't believe it themselves. There was also too many "whys", if god's all powerful why did he do that, why did he not do it this way? "God works in mysterious ways"...again, you're just making excuses.
Even as a small child I had amassed a mountain of science books for children like "1000 Qestions and Answers", "How The World Works" and "The Big Book of Knowledge" which helped me understand the Bible's falsehoods. Having a keen interest in science, at the age of about six I preformed a ground-breaking experiment, I asked god to turn my pencil-case into a car. The results were negative. "Don't test god" was the reply...he created the universe, surely this simple request would be a dodle.
One last thing; praying? I always wondered what people were doing in their heads when the teacher asked us to "bow our heads and say a wee prayer". Are they talking to god, can they hear anything? I came to the conclusion that they were doing what I was doing - pretending.
For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.
