Yep, according to recent knowledge we all have body map in our brain. Whatever happened to us is immediately transposed to this body map, and obviously connected to feeling self. I can imagine instances when this map and feeling self could be manipulated or maybe broken with brain injuries. For example out of body floating experience manifests itself when your body map is shut down with oxygen deprivation during accidents, electric stimulation of brain, or during meditation. Likewise we have a special map of outside world in our brain, working in relation with self map. Therefore for some people might be possible (genetic predisposition) to feel some emotions outside their body map/the self, in outside world spacial sector in brain. This might be felt as presence of spirits or gods outside our bodies. If somehow feeling of love moves out of "self map", it might give sensation of loving god watching you, or that you love the whole world.
We can only imagine how difficult it is to convince such person not to believe in supernatural. Logical arguments are not much against feeling of god's presence.
I'm somewhat spiritual person and former believer. In my case my logic analyzing my life experiences and acquired knowledge has lead me to conclusion that the world as we know it can exist and operate without help of supernatural. Other words, my logic don't let me believe, though I certainly could.As with many other things, genetics probably have a great deal to do with it but life experience helps shape what role those genes have in our lives.
