Mortal conception of the infinite

I wonder about the concept of a god (s) sometimes. I completely agree that there is a higher level of consciousness. But inherent in that reality is the fact that a lower being, by nature, cannot conceive the wholeness or complexity of a higher being. Given then, that when it comes to our ability to comprehend something completely beyond ourselves, I just don't get was the fuss is all about when it comes to religious conflict. We're all puppets in that sense, build to serve our maker as it were, so why would we do either of the behaviors that are hallmarks of our species; killing each other over details, as well as subjugating our environment to the point of our own detriment. We haven't killed whatever god each of us believes in; we failed it.
