"Why did humans evolve to believe in God? What is the point in this belief? Is it responsible for the upkeep of natural balance? Or is it just a temporary flaw in human evolution that is being fixed."

An intelligent question.
The answer is, that it might be "temporary", but it is not a "flaw".
For many thousand years the Religion was and is the only practical way to convey Philosophy and Morality from generation to generation.
For the science to challenge its validity is stupid, since it has totally different abilities and goals.
