I fully disagree with that article.
#1) Most civilizations never believed “in God”.
#2) People who are not introduced to god beliefs don’t automatically invent god beliefs.
#3) Most organized religion in this world has been spread from a few powerful sources, it hasn’t independently arisen.
#4) There are many cultures who had no beliefs in any gods at all of any form whatsoever.
#5) There are even cultures, described by Darwin himself, who had no beliefs in “spirits” of any kind.
“God belief” is something that has clearly be culturally cultivated, it is not a biological trait.
“God belief” may be reliant on some fundamental biological traits, but these aren’t specific to god belief. These traits are generally things like pattern formation, drawing conclusions between causes and effects that are not real, (i.e. I danced and it rained, thus my dancing must cause rain, etc.), leader worship, and the desire for social control.
These traits are probably biological in nature, but they don’t constitute a biological “god belief”. They may be appropriated through social constructs into a “god belief” but it is the social construct that creates the god belief, not biology.
Again, this is easily solved. Raise children without ever exposing them to the concept of gods and see if they invent gods. I’d bet any amount of money that they wouldn’t.
