The soul of a person is his spirit. of course Adam and Eve both were created dead until God breathed the breath of life into them and then man became a living soul. which is the spirit in the body that causes the body to function. hell starts just below the ground and extend to the center of the earth. anything below the ground is hell. Amos 9;10 gives you insight on this. your body returns to dust just as God said it would, whether it be dust or ashes,or swallowed up by the sea it turns back into what it was made out of. The wicked go straight to deep hell where there is no escape. whether it be hell or paradise ,you return to God, and he give you whatever reward you deserve.
