from Why I'm an athiest
First off, one should know that I come from a very religious background. My grandfather has been an Apostolic Lutheran pastor for my entire life, and my mother became "born-again" at some point after getting pregnant. When I was a child, the family would play "Bible Trivia," and I kicked butt because I enjoyed me some Bible stories.
Around about the seventh grade, I started thinking, and one thing that kept going through my head is that the deck was stacked against humanity from the start, if one believed the book of Genesis. God was omnipotent and omniscient, so he knew exactly what sort of creation he'd made, and the consequences thereof. So, here's Adam and Eve, with one rule to follow: don't eat the fruit of the Tree of Knowledge. What follows is well known of course, the "Fall of Man." What got me though is that God should've, indeed must have, seen it coming from the very start, and took no steps to prevent it. There are many that could've been done: don't let Satan in the garden, don't make the bloody Tree, make sure Adam and Eve really are obedient and not prone to disobeying just cuz of a few honeyed words, just to name a few.
Does anyone else remember playing Bible Trivia? I was not the best player, although I could hold my own against most. :-) I was pretty good at New Testament and Pentateuch, but major and minor prophets could stump me pretty easily.
On a more serious note, Lucien illuminates an issue that I think is common with people who leave their original faith for a new formulation of the faith, or even no faith at all. The stories or the meanings behind the stories no longer "make sense."
