Religion is an old form of it is what is, hope, direction, tradition, and community.

Can’t explain a thing or understand it God’s will or only God knows. Can’t do anything to help a person because they are in surgery pray or talk to God to wish for good outcomes.

Don’t feel loved or know what to do or wanted. God loves you, will show you the way, and wants you.

Most traditions and communities in the west were founded on a religion so you have hundreds of people to connect with at a church and maybe millions world wide that will help. Those raised on books of wisdom or what is right and wrong still tend to keep the values even after they move away from the religion but realize they can have values without divine beings

Lastly control. Just like businesses it is easier to control people under a religion so if you can get people indebted, traditionalized, and ostracized otherwise. You can control people easily. Lots of people don’t know what to do and why trust another human being but if a human being says wisely God said this it is easier to accept and gain a direction
