As you wish but with regard to the Abrahamic religions I think one can see three things. Moses brought the law, rules to live by that any person whose self respect is in tack manifests naturally. The law was a reflection of how a person who is whole responds to life naturally and within the limits of human evolution at that time. That religion went south with the assumption that all one needs to be enlightened is to obey the law. This closed the door to the possibility of salvation to any who had sinned and believed such nonsense. That is why in the next phase of revelation Jesus brought forgiveness for sin. It is not the law but the spirit of the law that matters and that the concept that being a worthless sinner can be transcended by ego death, surrender to God in the real faith that one can be forgiven, that one can forgive oneself. Naturally that quickly became a way to skirt the real self-transformation required, the experience of grace, the route around the ego, where one can pretend one has been forgiven and keep right on sinning to be forgiven again and again. Islam reconciles the law of punishment and forgiveness with deep natural common sense. The perpetual sinner faces punishment for transgressions right up to the point where the request for forgiveness is expressed. Then that person is bound by contract never to sin again. In this way both the base animal in us that seeks revenge and the saint who dispenses compassion can be satisfied. So I do not accept your 'that's all'.Religion was created to explain things that people without access to science couldn't explain using their limited knowledge. That's all.
And I'm not trying to be mean-spirited, but that really is how the first religions got started. Everything that has followed since is just an extrapolation of that.
You are, in my opinion, just trying to explain things without the benefit of an ancient science of awakening you have not been educated in. I can't do anything if what I say makes you mad but from my perspective it's actually quite funny.
Once, long ago, a psychologist I had sought counseling from told me I was being defensive, to which I replied, "I am not". Imagine the surprise and chagrin of the idiot who fell face first into that classic. God knows how many other such whoppers I've committed and never later realized.
