To answer villian's question: Heavan is something peole made up to convince people that they would go to a better place after they die so they wouldn't wake up an realize what miserable lives they have. It was especialyl useful in the serfdom and with slavery, becasue it didn't matter how much backbreaking labor you did or how worthless you are...it'll get better. 😄
well it seems that u have a pre disposition to all religions with "heaven" there are a few so i would say first u should ask urself if u truly believe in these places of afterlife. after that then u should delve into the most suiting to ur beliefs.
as for me im a satanist/pagan, i do not define myself to a single religion because no religion contains all that i believe and disbelieve.
finding a religion from nothing is a quite daunting task so i wish u good luck.
