Trust me if; and that is a big if, religion dies off it is not going to be in our lifetime. Fundamentalists for example do not care about facts nor science they take whatever the bible says literally no matter how stupid or insane it may seem. Because they base their entire belief system on faith they do not see the need to provide an explanation for contradictions in their scriptures. Not to mention the large number of zealots not just in Christianity but in Islam as well. Most people who leave one religion usually replace it with another religion and do not necessarily become atheists or agnostics.
There is nothing people will not maintain when they are slaves to superstition
