I am so thankful I figured out religions was BS before my teens.
That is why most who have doubts continue on... they don't want their lives disrupted.
Humans are animals that evolved in groups for safety. We tend to mostly associate in groups today because we are drawn into groups instinctively (animal instincts are still present in humans, and usually expressed as emotion). Mos people have a fear of leaving a group tht they are a part of, because they feel safer (instinctually) when they belong to a group and have place in that group. The idea of leaving or losing their place in a group causes feelihngs of fer and insecurity.
Like it or not, your place in a group may add to your status and attractiveness to others, jus tliek in animal groups. So, stepping away from a group also involves a loss of status among your acquaintances and group members.
It takes a lot of courage to leave a religion considering that it goes against our innate animal instincts to leave a group in which we are established and have a place. Because as the Meme says, you do have start over for a large portion of your life.
Isn't it odd that people feel a sense of loss when they give up something as vile as religion? It's like climbing out of a cesspool and washing all that shit off in the shower and then looking down the drain with remorse because you are suddenly clean. People are very strange indeed.
Think it is more of a - - - wow, I spent so much of my life covered in shit. It is sad I wasted so much of my life in that cesspool - Imagine what I could have experienced, if I didn't waste so much of my life in sewage.
I was thrilled, actually. After I read the Sumerian texts my main feeling was profound relief that it was all a lie after all. I always wondered why we were told to love everyone while the Hebrew god ordered people stoned just for picking up a stick on Saturday. Sick.
