I dont know what kind of a fetish people have for monotheism. Sure, its very neat and nice pick all the glorious theories to believe in, in which case you will be surrounded by eternal white light when you die, and that everything about afterlife is so goddamn positive, and that its permanent. Monotheist is fucked up, if you ask me.
Also, i dont know why everyone thinks life has a "meaning". Sure, its logical for existance to be continual, yes, but what the fuck implies that life has a meaning? It may mean something to you or me, but i dont think there is a divine reasoning behind existance. And even if so, what do you need the meaning for?
