For some religious theists, their religion and religious beliefs are so important to them that they can't imagine anyone being without a religion of some sort. For such people, religion occupies such a fundamental and necessary aspect of how they live that they insist the same must be true of everyone. Thus everyone must have a religion of some sort and it's impossible for anyone to live out one. This includes irreligious atheists who insist that they really don't have any religion.

I know many people have a god gene that makes them believe in a god or even many gods but I have never really belived in god.
Early in the 20th century, Joseph McCabe wrote a book called The Story Of Religious Controversy. In chapter 2 of that book, “The Origin of Religion,” he looked at anthropological studies of the most primitive societies then still to be found on earth. It turned out that those societies did not have religion, nor did they believe in gods. He said that the first indication of other-worldliness was the so-called shadow world of primitive societies one or two steps up from the godless ones. People from those societies believed that their shadows and reflections indicated the existence of a shadow world, separate from the everyday world. Only at a higher level of culture did societies begin to believe in gods. So, according to McCabe, the earliest humans were probably atheists.
Of course, McCabe was looking at existing primitive societies in his then modern world. Then, an obvious explanation for their lack of progress compared with his society would be their lack of gods and religion
. Did McCabe ever find an advanced religion without gods or religion?
In the last sentence I meant an advanced society without religion.
It should probably be noted, however, that the reason why those societies were so “advanced” was because they were built on the backs of slave labor. Religion commanded the first slaves to do their master’s bidding for fear of what lay in the afterlife.
no, they are not. the only people that cling to old superstitions and make-believe nonsense are religious adherents. i have and need no religious dogma or doctrines and tend to agree with Freud’s assessments that religious belief is a symptom of mental illness.
