There is no heaven or hell.
Once you die, it is all over.
Believe what you want, I’m a
Buddhist.
Once you die, you will probably prefer heaven.
Don't believe what you want, since your belief will affect where you go.
Fortunately, God did the heavy lifting; and promised to indwell us and to change our very nature to restore our right relationship to Him and bring us to heaven.
I'm a Christian.
Full Disclosure:
Since you're posting this on a "science" thread, I expect the atheistic evos (if they are sincere) to swarm over you, demanding physical evidence for the historical anecdotes and theological teachings of Buddhism; and demanding that only evolution be taught in schools in those countries where Buddhism is a major faith.
And then to repeat the process in Israel.
And then in the Caliphate.
