People believe in God due to the lack of time to do a good philosophy to understand reasons for life. But that is very mind intensive, hard and can cause major headaches. Religion is basically generalised, simplified life philosphy, wich has been abused by churches to obtain money, and maintain power over society.
Especially in the middle-ages, when they said "Do this or you go to hell". And so they had complete control over everything. They executed philosophists that shared their ideas because that would undermine their power. We have grown over this, and I think it is about time we drop churches as churches, and use social meeting spots to discuss religion, the philosophy version. So we really need to get over the part of "Do x or you go to hell", but basic religion is good.
Addition-edit:
The bible is pure imaginated stories bundled together, with the tag "Religion" on it so everyone that is religious buys it. Seeing most people don't like to urposefully think about the meanings of life, alot choose the already-present, packaged and easy-to-install religion. Therefore the book is sold like, a billion times?
Tl;Dr:
Religion is simplified philosophy.
Because I stand up for what I know is true Im brainwashed. :D
You are very dumb for thinking your opinion about something is the actual truth.
Hell, we might evin be situated in an atom core that is rediculously oversized, and wich is like, an element on a superscaled other universe.
