>>8079897Gods exist for three reasons: To explain what you cannot explain otherwise (thunderbolt and lightning -> Thor), to be an emotional support blanket (i don't want to cease to exist -> afterlife) or to control the masses (although you can also achieve this without a god or religion).
If you are reasonably certain you can explain the world trough science you don't need the first, if you are not scared to die you don't need the second and if you don't want to impose your will on the world trough a bunch of fanatics you don't need the third.
