Personally I don't care about downvotes unless it accumulates, then it hides my comment -- kind of virtual censorship which atheists decry about re. religious folks, but engage in the same when they have the power

Entertaining the possibility of what we don't know, or simply acknowledging that other explanations may exist is the purpose of most discussions.

As for you reply, that is one explanation and a solid one. I just believe that there is so much we don't know about the brain and our chemical reward system. It was not until recently we discovered how "addiction" changes brain structure. There may be a desire to gravitate toward religion/spiritual entity because it releases excitatory neurotransmitters (eg dopamine) just like when we see food, engage in sex, or feel loved.

Psychology studies have already shown how having faith is protective against depression and isolation. So perhaps, it may not be as easy as "let go of faith", when we keep getting drawn to it and there is a reward system within.
