The reason humans stopped inventing Gods is they came to the truth. It was sort of like doing R&D, with respect to a novel out of the box concept. Religion is unique to humans, therefore religion was way outside the box, with respect to animal instinct. The lion cannot hunt if he hallucinates. The founders begin their research by trying many things, until they finally discovered that which fits the bill. After the research was complete, the task became development; expand upon main religions.
My approach towards religion and God is different from most. I walk a line between science and religion that treats both with credibility. If you study collective human symbolism and human psychology, it is well documented that the human brain can spontaneously generate symbols, such as in dreams. Many of these spontaneously generated symbols will be the same for all humans, regardless of culture. These collective symbols appear to be connected to human nature; human DNA, and not to cultural knowledge. They are innate to the human psyche. For example, most religions have a mother and/or father analogy. Although superficially different, as to who this may be, at the core all of these, it symbolizes a natural connection between the individual and the parent(s), which commands respect, love and trust, based on the configuration.
Collective human symbolism, if you delve deeper, since it is common to all humans, will also define a hierarchy of symbolism, that essentially maps out the human psyche. Religions project this map. Once the natural maps were completed, after centuries of R&D, there was no real need to make new maps, since human nature has not changed in that time. These maps are not concerned with manmade, but with the natural terrain. Atheism is more about manmade maps; personal and cultural collective, which tend to change.
In terms of mapping the human psyche, the center of the unconscious mind is what is called the inner self. The inner self is often the projection factor that is personified by the central God. The inner self is natural therefore it is morally neutral. It is not easy to explore the psyche that deep down, because there are many hazards and pitfalls. Religions allow one a way to tweak the operating system, down to the inner self, through a bridge which has been constructed. The proper attitude is necessary; faith, since the proper feeling is important to human nature; to make use of the commands lines. The natural command lines is why religion is often scary to atheism. Religion does not need drugs to get altered states of the psyche. It is done naturally.
The inner self runs the personality firmware connected to our human nature, from which the symbols appear. The religions of polytheism mapped the psyche as deep as the firmware. Monotheism got the map deeper, all the way to the inner self. Christianity is unique in that the one God; inner self, was replaced by a trinity; father, son and Holy Spirit. The implication is either new natural firmware evolved, or the inner self set point was elevated, or both.
