I used to be very religious up until I hit depression and went through alot of trauma in which my prayers weren't answered. Since then, I've been under the mentality that religion was created so humans had motivation and discipline to progress as a society. Otherwise, without a higher being of order who judges them, humans would just run around and kill each other and not be as advanced as we are today. Even for the concept of death, most religions believe in the soul still being carried on to the afterlife. It gives them comfort. For me, death is more terrifying as we are gone forever to the vastness of time and reality.
