Why do humans search and/or reach for God?
If they are honest with themselves it is because have a fear or death or of non-existence. Or they draw "power" from God. A small few (when they are truly honest) admit that they search for a God to explain existence. Why do so many prisoners suddenly "find God"? Is it to gain control.
In my opinion, the concept of God was needed to offer a way for people to organize things which they failed to understand. True we probably have new things today which we fail to understand, but we have precedent for organizing processes to explain and discover these things. Previously, discovery was discouraged by the churches and zealots who knew they would lose power if people surrendered their superstition.
One person I wrote to explained their reasoning on this subject as follows:
So what does God have to offer you?The attraction of theism, as opposed to naturalism, is the institute of petition; namely, that mankind can petition the gods to change fate, thereby having some control over fate, whereas under naturalism fate is blind and cannot be controlled. Sincere prayer, and belief in its effectiveness, is the clearest outward sign of theistic belief. The core of theism is a belief of external sovereignty over fate, whereas the core of naturalism is lack of belief in such.
