Guys he wasn't saying that there was no proof for air and oxygen, so stop trying to sound all smart and stuff. He was making a metaphor to help those struggling with their faith. Back off and stop being so harsh on those that want to help and find other religious people such as them selves, if you wanna go bad mouth religion that's fine go find some people who are interested and agree with you. Not here, you all constantly hounding them about how their god is fake and they're ignorant for believing that is not doing you or them any good. After all what do you get from making them question themselves and what they believe? If you are honestly curious about what they believe then ask like a civil, responsible person no need to be a dick about it. [spoiler]Just be nice guys, no need for such hate and hostility towards people who don't believe the same as you![/spoiler]
