How Atheists explain this phenomenon? - Brazil
The psychological reasons for belief in an invisible deity are not mysterious. One of the most obvious is our tendency to assign agency to random events. At one time humans believed that thunder and rainbows were acts of god. Famines are storms were assumed to be signs of his displeasure and of course having made the right sacrifices the storms passed.
We evolved from a long line of ancestors who assumed agency. Those who dismissed the noise in the grass as 'just the wind' tended to get eaten on the odd occasion that the noise was in fact caused by a hungry tiger. False positives are less costly than false negatives.
Then there is the understandable assumption that design requires an intelligent designer. Natural selection has made that belief redundant.
Worship of a particular deity also served important social functions. The 'hive instinct' that is triggered by religious rituals increases group cohesion. Belief in an invisible but all-seeing judge also provided a powerful incentive for good behaviour when other members of the group are not around.
Finally, and most obviously, is the desire to avoid death and the wish that the injustices of life will be put right in the next.
As an atheist that is a very brief explanation of how I account for belief in the supernatural.
P.S. - Brazil were very disappointing yesterday. 'Football's coming home...'
