If you're addressing people who only believe in what they can see with their eyes then the answers you're going to get are obvious. Of course such a person wouldn't believe in 'souls' so there'll be nothing to go anywhere besides what gets burried in the ground.
Ecclesiastes 9:5 says that when a person dies he or she is conscious of nothing at all. So whether you believe in God or not, once you die, that's it, you go to the ground. Jesus did speak of the hope of the resurrection, and only God can make judgment respecting that hope.
