"After death"

Litterly every religion: "you only go to heaven if you believe in [religion] and live after its rules"

Well i don't know about you but a lot of people lived and died before those religions even got invented, so its kinda hard for me to believe that to be true. 

I think after you died what ever you think to be true will become true. You think after death will be nothingness? well thats what you get. You think after death you will be reborn? Sure just ask parallel universes and you end up in a close to our timeline and get born there. The universe does not give a single shit, there is no right or wrong from the universe prospective so karma only manifests in you. If you feel bad become you fucked someone up the "karma" is that you feel bad, you can go and talk to that person and try making yourself feel better but its obvious that asshole people can just be as successful is not more then nice people. Nothing will get judged when die unless you believe you will be judged. If you think you will reach the holy land after death, well thats where you end up. If you think are where a terrible person and deserve hell for it, well your worst fantasies will come true. You believe you will meet your loved once and stay with them till the end of time that is exactly what will happen but that does not need to be the case for the view of that said loved one. I believe your memories of those people will manifests as your reality meaning that loved one might end up in a totally different scenario from their prospective.

and thats why i will after i died end up in a different universe, possibly as a different species take of my "headset" that says "Human game" and walk away. In an endless loop of lives and universes in changing dimensions and timelines. Maybe we will meet again in one of those other places. I am playing a game that never ends :)
