Why do we need religion?

No disrespect to people that are religious, but i think religions are a complete waste of time. It just gives people false hope. Yes, religion can show people how to live the right role of life but who says the is a correct way to live?. I know stealing, killing, adultry,...ect is bad. I didnt need to go to church to figure that out. Religions are there to explain the unexplainable. When there is a problem in life and no one knows why it's happening to them, they tend to seek higher authority. The explanation may not be true, but it gives a sense of comfort and ability to process and accept hardships in life. But at the same time alot of people suffer by religion. People use religion as a form of control which totally contradicts what religion is all about. Whats sad is i do believe religion was created to control people. Some may try to do it indirectly but they still have some form of control of how you are living. It makes me so angry. You give people a little power and they abuse the hell out of it. You got people ready to give there lives for a religion and what do they get in return? Some words of wisdom?  The promise that you will make it to heaven?Even though majority of preachers dont even know if heaven exist. What really bad is people dont even question their religion. They just sit back and believe everything that they are told. If your gonna follow something wouldn't you first find out what your following? Dont just assume your preacher is right. Take some time to read the bible yourself. Religion = Hypocrisy plan and simple. I can't solely blame religion though. Religion is man made. The bible was written by man. It didn't just fall out the sky. Someone wrote it. Thats goes for all religious writings. It just show how simple minded our society is. We can't even figure out how to live our own lives. We need a book to tell us how. So, to put it simply, we don't need religion, we need reality and a lil common sense.
