Christianity was NEVER the first religion...if you believe this...well, what can I say...you're quite gullible. The first religions were pagan religions that focused on the earth and nature...why?! Because you can not control nature, and so it must be a God. As for the Bible being different...you can say the exact same thing about the Qu'ran. Or the Sikh book of worship (or...technically, their God). Each religion in its own way is unique and should be looked at as special in and of itself. Which is why I don't choose to follow one religion but make my own up. Choosing is too hard, because all of them are right to a certain extent.
