Here are some basic things, the predictability of which most people in the developed world enjoy.

1. Clean water 2. Roof over the head and the sense of safety that comes with it. 3. Basic food.

A sense of community and friendship is probably the only basic human necessity that is not certain in the developed world.

Now imagine a world where none of this is can be taken for granted. You live under a constant threat from various sources (disease, wild animals, other humans out there to steal, loot from you etc) , there's not enough food, water and on top of that you're lonely. Religion is one driving force that helps people through these.
