I agree, everyone has a unique perspective based on their own individual knowledge and personal experiences. This knowledge and experience is subjective due to the numerous variances that help shape and mold the human Psyche. Through the eyes of another, definitions and interpretations tend to vastly change, for example: "One mans trash, is another mans treasure. One mans pain, is another mans pleasure."
   Religion or better said, spirituality often becomes mans basic necessity, it gives man a sense of self, a feeling that maybe the life he lives and experiences is actually bigger than just himself. Religions can be dogmatic when taken to the extreme of course, but the underline principal is that religions contain basic morals & ethics that a religious follower can aspire to live by.

Hypothetically speaking for arguments sake

Example: In the religions of Catholicism and also Judaism, there exists a set of 10 basic commandments followers must adhere to.

10 Commandments

1.“I am the Lord thy God, thou shalt not have any strange gods before Me.”
2.“Thou shalt not take the name of the Lord thy God in vain.”
3.“Remember to keep holy the Sabbath day.”
4.“Honor thy father and mother.”
5.“Thou shalt not kill.”
6.“Thou shalt not commit adultery.”
7.“Thou shalt not steal.”
8.“Thou shalt not bear false witness against thy neighbor.”
9.“Thou shalt not covet thy neighbor’s wife.”
10.“Thou shalt not covet thy neighbor’s goods.”

Now, looking at religion through an outsiders perspective, the Commandments 1 - 3 might seem a bit absurd, especially to an atheist, while commandments 4 - 10 seem like basic codes and tenants any man regardless of their race, political affiliations, gender, sexuality, religious doctrine, or creed could live by.
