Religion is a must for every human whether educated or not. Even atheism is a kind of religion. Religion is based on some beliefs and ideologies. Religion is meant to show a way of life. For this it lists out some rules and regulations a human has to follow. Differences in religion does not make it unnecessary. Atheists believe that there is no life/re-birth after death. If every human is atheist then there will be high degree of immorality as everyone (with few exceptions) would think of experiencing pleasure in this world. Religion has controlled vices of humans at least to some extent. If I have a problem/disease which I cannot solve/cure with available options in the world I can pray God. Whether my problem is solved or not at least I will get some relief/moral-strength. What will you do in that case? Fear of hell prevents/controls me committing sin to a great extent.
