If there was no God to speak of, would people still feel a spiritual, God-like sensation?
I imagine that it's highly debatable whether or not that's close to how the concept of God originated. I agree that mystical experiences often lead people to contrive their own religions, like Ontophilism, for instance. :joke: Our natural desire for meaning is insatiable
I think what I have described is really the only thing that makes sense though, because it actually could be the case without question. For instance when atheists insist that God does not exist, not only is this debatable, but it is also an unknown, as in they only believe that God does not exist, but they cannot know this for sure. Moreover, the "God" that does not exist could also be the same God that is a matter of what I have described. That is, people long ago developed the concept of God to define a spiritual presence that they likely felt and wanted to give meaning to it.
Not only is my description highly plausible, but it would also mean that "God" is indeed no more than the identity given to the spiritual being whose presence was felt by people long ago, and thus would essentially negate the argument of atheists and theists that God does or does not exist, since "God" would in essence only be the name given to a spiritual presence that was felt. Thus, God exists in that aspect, but would otherwise not exist.
If a theist were to simply BELIEVE that God exists, that belief would be without a strong argument, since there is no evidence to support a mere belief, and a belief is disputable by nature.
