The biggest problem is religion stands for faith which we can not prove yet we assume it to be true. The more we associate with this, the more we drift away from reason. The irony is we associated long enough. And now religion stands for ourselves. It is now who we are. It is the very core of human being. Because it's easier to trust religion as it gives comfort but at the cost of rationality. And human being by nature is greedy. We always want more. But resources are limited. And there is nothing other than faith which can give us the hope that we will get what we want. So you see there is no way out.
