I wonder if atheist evolutionary scientists like Richard Dawkins, who call for the elimination of religion as soon as possible for the salvation of humanity, I wonder if they ever considered that religion, even if was wrong, might be more "fit for survival" from an evolutionary perspective than atheism.
Religion has existed since man has been walking upright, and it is showing no signs of going away any time soon. The reason is that it works for humans. Otherwise they would have done away with it.
It is one of the most powerful forces in the world. It is highly unlikely that Muhammad could have inspired his illiterate people to build and expand an extensive empire and civilization without religion.
Wrong or right, as long as it works, people are going to depend on religion at the group level for motivation, human social organization, and spiritual and emotional livelihood.
The best that secularists can hope for is that religion will enter a more liberal era where its negative effects are ameliorated.
