If you create a super hero then you must also create a super villian fro him to fight.
Therefore when man invented God he obviously had to have a realm so they put him in heaven. Now they had to create the Devil and grant him his realm of Hell.
In reality there is neither, it is all from ancient stories told by those in power to keep the minnions in line.
Be goodly and be rewarded in heaven.
Be evil and you will be punished in hell.
Never understood the concept myself. Logic dictates that if the Devil is evil, and you were evil yourself and ended up in Hell wouldn't the Devil welcome you ???
