Neither exist, for those places to exist there would have to be a god and a satan. We are all just animals, no purpose other than to make more of us and eat. Religion has hurt this world more than any other thing could, except for maybe a large comet. I think that it is absurd to think that just because we are the smartest(maybe) creatres on this planet that we have some sort of devine entity looking over us. When we are dead thats all that we are is dead, no soul just a blob of goo and a big brain. All of this is my opinion, I dont try to push my views on you dont push yours on me.
anyway
Heaven :A nice tourqy car with a never ending windy road
Hell :Being stuck in a waiting room with annoying kids, and more annoying parents.
