If you really mean that, your idea of religion is very sick, twisted and wrong.Because religon is the only way of "control", rather it be the government or some other bs that they have on the people, because religon is a major tradition, and nobody can even prove that there is any kind of god or superior divine entity of any sort. People who arent involved in a religon know the real face of the world because they dont need to have fears, a church is a place to escape to, to hide fears. Having no fear is how somebody unlocks their potential as their own individual, religon allows a thought to come in mind that there's a place to go to in time of some sort of despair.
There is no need to prove the existence of god for the purpose of Religion. Even though people, wrongly, try to explain everything with religion, Religion isn't a scientific subject. A religion is just something you use to live your live the best way you can. Some people need God to be good, others need Gaia to feel harmonious, others, like me, don't really need any of those things, but that doesn't mean that this is our religion. Religion only serves for you to think of your live and give a meaning to it. Religion can't explain why the earth was created. Religion can't even explain why flowers blossom (Don't try to say it can, because you'd only be fallin on the mistake I've warned you in the beginning of this paragraph), but Religion can give you a path, and a meaning.
Your next part of the argument is now very confusing. What do you mean people without fear progress better. That's just wrong. And what are you trying to say with "fear"? What's the meaning of fear to you? How can you apply it in this subject?
