Yup, There’s a reason why double-blind studies were developed: Bias is a very powerful thing. 

When trying to climb out of that delusional Witness sink-hole, it was really hard to give up things that I WANTED to believe, especially with tantalizing "evidence" being dangled in front of me that superficially supported those beliefs.
 It feels GOOD to believe I am at the tippy top of all creation, a special man living in a special time with all the answers and personally loved by god. But it only makes sense if you are conditioned to filter out conflicting evidence. 
 
-If I’m running around outsmarting tigers and killing mammoths, and suddenly lightning comes out of the sky and kills my buddy, I think a big strong invisible angry man in the sky is a pretty good theory, based on available evidence.
-If I’m plowing a field with my oxen in 15th century England and I suddenly start hearing disturbing voices that no one else can hear, I think demonic possession is a pretty good theory, based on available evidence. 

   We’ve learned an awful lot about our world and clear patterns are emerging. Fewer and fewer phenomena require supernatural explanations. The center of the universe is getting farther and farther away from "me".
   Whether or not some unimaginable discovery will be made in future that will change all these patterns, who knows. But an overview of what we know now gives a pretty grim outlook on the "truth" of established religions.
   I’m thinking that the "Javecas" of the future will be condemned to more and more convoluted arguments in search of a plausible defense of their chosen beliefs. 

   No disrespect Javeca, I’m impressed by your semantic gymnastics and logical contortions. I just think you’re making a valiant effort on a losing team.
