I know that I'm taking this out of context, but the following quote pretty much sums up why I think organized religion is so laughable:

3. What if you are wrong? There are thousands of gods, which one do you believe in? I'm pretty sure whichever it is it'd be better to not believe in any of them rather than worship The One's rival.
It's funny how many gods humanity has invented. Yet, everyone is so sure that 'their' god is the correct one. They just know.
