I'm sorry, I really mean no disrespect.. but how can some of you people believe this stuff?

It's like you live on a completely different planet than I do.
If it helps you, that's great I guess.. But religion makes no sense to someone like me. I mean.. how would I even pick one, if I wanted to? Whichever one suited my ideals best?

lol.. That's ridiculous. The way I look at it, there are as many religions as there are people on this planet. It doesn't matter what you believe in. It's up to you whether you want to be a good person, have a prosperous life. People of any and all religions are capable of being happy, positive, productive people.
Unfortunately, religion is and has often been used as an excuse for behavior that is shunned by any "good" society, religious or not. The hypocrisy is just overwhelming. I dunno. It's like trying to fit a square idea into a round hole. It just doesn't mesh with the repeatable, verifiable, indisputable, physical, tangible, observable facts. *shrug*
My (actually rather serious) question to you would be this: Of all the religions that have existed in the last 50,000 years.. How do you know you've picked the right one?
