Personal motivations for following a religion are probably as diverse and unique to the individual as fingerprints.

A unified set of “motivations” doesn’t emerge until we back away from the individual and look at the phenomenon in the light of biology.

H.sapiens is not evolved, biologically, to function in complex, agriculture-based societies. In evolutionary time, agriculture and its civilizing influences arose too quickly for our biology to adapt, so we made that adjustment culturally.

The Christian mythology actually tells that story pretty accurately.

We were living relatively worry-free lives in small, nomadic, hunter/gatherer tribes, pretty much the way natural evolutionary forces designed us. This is analogous to the Garden of Eden where everything is as "God" (nature) intended.

When we chose to tinker with "God's plan" and learn how to grow our own crops (eat the fruit of the tree of knowledge) we were "cast out of the Garden and condemned to toil for our sustenance". No longer could we just stroll about and collect what God had provided, but now we must conform to the complexities of intentional farming, and markets, and money, and land ownership, and permanent housing, and legalities, etc., etc.

This required modifying some of our natural instincts that were not conducive to living in close quarters with large numbers of strangers whom we nonetheless must trust and cooperate with in order to survive.

The thing that we call "religion" today was nothing more or less than the cultural adjustment that bridged the biological gap between hunter/gatherer and agriculturalist societies, without which the evolutionary mismatch would have done to us what it does to all species that operate without benefit of capacity for complex culture when their environment changes more rapidly than their biology alone could adapt.

Culture is the shock absorber on the bumpy road through environmental change, which would otherwise shake us to pieces, as it has done to every now-extinct species. Laugh at shock absorbers if you must - improve them if you can - but remove them at your own peril.

Yep that is it. Never have to think, never address a moral problem (there are none ). You only have to read one book, and if that is too, hard someone will read it for you. And you will always be told that you are going to get everything you want, later if not now, so that you never have to take the main challenge of becoming adult, which is the understanding that "I want." is not the same as " Its True". Perpetual spoiled childhood.

You are talking about people that follow governments, why do you say religions?

Religion ... pure and faultless is this: to help widows and orphans in need and avoiding worldly corruption. James 1:27

What is the ultimate aim of those who follow governmental?

Should be the question.
