Do I really need a religion?

On the last day of school I was reading some of the stories from a childrens bible. None of it was making sence what so ever. It was going against all logical thinking pretty much. I got to the part about Noah's ark untill I just put it down. I feel like I need something to belive in because like what's the point of living if I don't have anything. But I'm starting to think religion is all just a stupid sham. But then again I think about what if there really is a God and what if there really is a heaven and a hell. I also think if there is a God why dosen't he just prove it to me instead of leaving me here in the dark. All my friends and my parents say you just have to have faith but it just sounds like total bull ****. I'm in between a rock and a hard place. Can someone help me out? I feel lost. I'm almost 16, sorry for the spelling I'm on my Ipod. Thanks(:
