Well, by innate brain freakiness (a very scientific term, don't you think? LOL) I mean that it's been proven that electro magnetic waves interfer with parts of the brain that can create hallucinations. There are certain things we naturally do that change brain chemicals, perception, neurological functions.
It's also been proven that intuition and empathy are normal human functions that sometimes seem paranormal, but aren't. Nearly everyone has these kinds of inexplicable experiences that get explained as "the paranormal" or "miracles" or "magic".
It's really magical enough to be a plain old human being, as it turns out. As I said, if you want to term the inexplicable as God or magic, be my guest.
Anything we don't understand is "magic" or "the gods" or whatever word you like for the inexplicable.
There's a whole universe full of things we don't understand. Eventually, we will understand more, but we'll never understand EVERYTHING. Not possible given our limitations.
I said to a good friend of mine who is an atheist (I have a good many atheist friends...after I quit demonizing "worldly" people, I've found some of their thinking a great counteragent to being raised in the non-logic of JWs that pretends to be logic) this very morning that if there is a God, then I doubt he's overly worried about getting lots of sacrifices and groveling from humans.
The very concept of a God that is greater than anything in this universe, which itself overwhelmingly difficult for humans to conceive of, rather precludes that a being that far removed from human experience would not have a great deal of interest in smelling incense, hearing chants or hymns or accepting the blood of animals or humans as some sort of guilt payment.
Those are things that have meaning to humans. Ritual makes strong psychological connections, lasting bonds, between humans and groups of people, there is the real meaning. God, gods, superhuman entities, why would they give a whiff about that stuff? They'd have to have a brain and senses much like ours for that to be so, and is that even possible for anything not human?
I don't deny that there could be a God, but the idea of God being your friend or your father is simply a human need. I don't even mind religion fufilling that psychological need as long as it's not harmful and we're all up front about the fact that we're all talking about "magic" here and not science.
After all, people can go to AA and say that the group is their "higher power" and it works exactly as well for them as people who imagine there is a God who is their "higher power" or support system.
We all end up parenting ourselves that is the goal of being a fully formed, mentally healthy human adult. If one needs to construct that self-parenting into a God or gods who act as that parental entity, then it's fine with me. I think some people actually do.
You can't make those needs that some religion fulfills for some people go away by ridiculing it or trying to deconstruct it. That just makes people defend it more. Even an abused "child" will defend an abusing parent. If the "child" is not abused, but feels loved unconditionally, they will have no reason to give that kind of emotional construct up.
Never tear down a person's emotional support system, regardless of how flawed or foolish or unreal you see it as until you can give them a better one to cross over to and replace it with.
That is why a lot of anti creationist arguments fall on deaf ears. It's why you can't convince Witnesses or any other cult members that they're involved in something harmful or untrue.
It's become their parenting structure, you can't take that away from them without a fight. It's not necessarily a matter of being able to reason or being stupid, it's a mindset of protecting the "parent" whether that is the religion or the God they feel is represented BY the religion.
This information is part of every what every person who helps someone exit a cult knows...but in lesser ways applies to getting anyone to get out of any irrational way of thinking.
Humans are so fond of large sweeping rationally unsound but emotionally satisfying and supportive concepts like God, patriotism, that sort of thing, that someone said that even if there was no God, we'd have had to invent him. We love to believe that the universe or the government gives a damn about us!
So, you can't deconstruct God or evolution or any deeply held concept based on emotional need without acknowledging why someone needs to believe this in the first place.
