I would argue a number of your points. Humans could well have evolved the concept of god in the manner you speak of, but this line of thinking cannot end there. That is a possibly testable hypothesis with observable results. It is reckless to draw any conclusions without the necessary support.
Humans may be inclined to do fantastic things in the name of god but that does not mean the name of god is the driver. The forces that propel humans forward have numerous possible and testable scientific explanations and belief in atoms and dirt or God and Jesus could very well (and probably do as numerous unbiased studies have shown) have zero effect on what drives us.
Mystical experiences of religious practitioners who have allowed themselves to be imaged (neural imaging) during their trances or deep meditations have shown very real and measurable changes in brainwave activity that are reconcilable physiologically with the feelings reported, from hearing the voice of god to out of body experiences.
If the complex systems theory can be used here then the evolutionary advantage of our intelligence is to allow us to expend this energy optimally and ensure our lineage continues to proceed with the process. Again, the possibilities you describe can't be ruled out, but they can't be concluded either.

My religion is the understanding of my world. My god is the energy that underlies it all. My worship is my constant endeavor to unravel the mysteries of my religion.
