Societies need myths. Religion is unifying people behind a common cause. Atheists reject this myth because its irrational claims cannot be explained scientifically.
Today we have many replacements for the religion myth, making it obsolete.
...
Religion is an ancient relic that will eventually be abandoned as such.
Let me rephrase this argument. Societies need moral codes. Religion is about unifying people behind a common moral code. Atheists reject this moral code because its divine origin cannot be proven scientifically.
As of today we do not have a functional replacement for the common moral code provided by religion. This lack is evidenced by the reduced wellbeing, health and fertility of those who reject the traditional moral code in favor of atheism.
Religion is therefore an ancient relic that is likely to grow in power and influence as that those who reject it are unintentionally reducing their evolutionary fitness.
Todays western liberal atheism is a "posion" because it is an worldview that gives you and the group evolutionary disadvantages. Thus western liberal atheism societies will cease to exist and become replaced with societies with an evolutionary functional worldview. A evolutionary functional worldview does not have to be organised supernatural religion as "christian" or "muslim" it must however contain a set of values which makes the members live a evolutionary successfull life.
...
Science does say how the world works and it does give you mental tools to solve particular problems but it does however not give you any values or instruction how to live your life whatsoever. For science it does not matter if you live or if you die or if you have a wife and family or if you become a drug addict. A successfull society must have someting more than science to guide its members in life.
Bingo we have a winner.
I would only add that I am not certain there is any evolutionarily functional worldview that does not include religion.
Religion has been there from the beginnings of human culture. We have evolved and adapted in an environment with religion at its core. The idea that you can simply reject it without very deep thought on the consequences is foolish arrogance. The data in the opening post indicate that those choosing to do so end up suffering from this arrogance.
Whether you view religion as an adaptive code that developed with and shaped human history or as divine wisdom handed to us by a wiser being the conclusion is the same. As of today religion may be a requirement for a sustainable and evolutionarily functional worldview.
