We believe in what we believe... You don't see me making a topic about why certain people are gay and why others are child enthusiasts...
Ima spare you the trouble... Why do people believe in religion? Because we believe something happens to us after death... The day humans began to bury the dead was the day we believed in the afterlife... Be it heaven or hell, something or nothing... religion is what makes us believe something is at the end... Depending on what religion you are in, maybe we arnt afraid or maybe its gona be a crappy end... No matter what, we all are in some sort of religion... Like it or not! lol
P.S. Im not spoiling what I believe so im not Bias...
