Can we assume that living is in fact "hell" because it is a godless existence filled with torture and suffering. While no existence is heaven because it's the perfect state where you don't need anything and you don't have anything.

Sure you can say that there is pleasure on earth but I think that time itself is torture. If you can be immortal and have anything and everything imaginable experienced trough infinite time wouldn't you suffer? Because you have a constant need for something new.

And what is all the pleasure on earth worth if you are approaching death?

So you might think that if you die you go to hell if you reborn, or go to heaven if you stop existing.
