If I were the creator of the universe, esp. the earth and its inhabitants, and I wanted everybody to know and worship me and follow a very explicit set of rules and guidelines, I might list all my achievements in book form, and I might even include all my rules in that book. Takes a load off my shoulders, right? I wouldn’t have to pop down here every hour and tap somebody on the shoulder and say “Hey, that’s against the rules.” Because if I wanted everybody to follow my rules and I had them all laid out in a nice book and people still didn’t follow them, I would do that. I would intervene. First off, it could serve as a pretty cool reminder that I actually exist. Second, some people just need reminders.
But being that I’m supremely awesome, supremely powerful, and supremely knowledgeable, the rules put forth in my book would be crystal clear. There would be absolutely no way whatsoever for people to misinterpret what I am saying. If I had to use my infinite magical powers to craft the book in such a way so that the words are phrased differently for every person just so they’ll understand exactly what I’m saying, so be it. But two people who have read my book would simply be unable to disagree on the fundamentals within: you would not have one person saying “Clearly if you read it this way, Dave says homosexuals should be put to death,” while another person says “Ah, but if you look at it this way it’s pretty obvious Dave thinks every adult person capable of decision-making, signing a contract, and saying the words ‘I do’ should be offered the right to be married.”
THERE WOULD BE NO MISINTERPRETATIONS. There wouldn’t be sects of people who interpret even two words differently in my book. Because I am awesome-fucking-possum and I actually want these people to obey my rules. They will be clear. I would use my incredible powers to make my rules somehow even more clear than the phrase “Don’t punch people in the neck.” Pretty clear, huh? Someone could misinterpret it. Not if I’m god though.
That is why religion is nonsense. Because the world’s three largest monotheistic religions (Judaism, Christianity, Islam) are based upon the exact same story, yet all three religions are vastly different from one another and each even have a whole sloppy slew of sects and cults within that disagree with one another. Yours is one interpretation out of thousands, and you learned it from your parents, who learned it from their parents, who learned it from their parents, whose interpretation of your religion was probably even vastly different from your own. And yet somehow all those other religions/sects are wrong and yours is right.
My role as the atheist/skeptic is not to say to you “Nope, you’re wrong. They’re wrong. Everybody’s wrong.” Rather, it’s to say “Seriously? Look at the odds. What divine knowledge has been bestowed upon you that makes you right and millions of other people wrong?” So what if it turns out you’ve got the right god? You‘ve probably been following the wrong rules.
