center of the earth

If I had no knowledge of science, I would imagine that the earth was hollow. And then that everybody who died, would go to the center of the earth after they died. Because since nearly everyone is burried, they would just slip through their casket into the ground aaand come back alive. The there would be another life down there, not quite like what heaven is cracked up to be, but we turn into the age that we most enjoyed in life, and then we can do whatever we want without being injured or getting any older, unless you want to get older. There is no polution or sickness, and there arent really any rules.
So technically, the real world would only be about 300 feet of compact dirt away from the "afterlife", but if anyone ever discovered that it was there, and they tried to dig, all they would find is dirt, dirt and more dirt.♥
