This is just another theory of a "smart" man. I have read/heard what a lot of intelectual people say about that there is no heaven because.. and they all give different reasons..
All i know is this.. There has to be a god, who then created this world piece by piece, the trees, the rivers, etc, and who created us..? There was just a big poof and everithing was created from nowhere... ? I dont think so..
All I can tell you guys is i was raised by my family to be a greater person that I can, i was raised to be humble, and nice to others, and I wont give up in my belief of god, I will always be bealive in him, and be there for him no matter what..
