So what? Why does that matter? What's the point? If God doesn't exist, does exposing that fact make life collectively better?
This is an odd and irrelevant argument. Facts make us uncomfortable, therefore what is their use? Belief in a god has done much over the years to suppress progress.
Yet that aside, your arguments are full of logical fallacies. There are more atheists in Europe, therefore, they can't pay their pensions?
The Netherlands have very secular societies, yet when measurments are taken for happiness, they always rank the highest. Is it atheism? Is it socialism? I don't know. It makes no sense to draw a correlation, when coincidence, or another factor---or hundreds of other factors could be contributing to the numbers.
Appeal to Consequences of a Belief
This argument is based on holding that what a person "wishes" to be true, must be true, because the alternative is too undesirable to consider.
