That's a ridiculous statement mate. You can't seriously suggest that the scientific community are the only people that can offer anything in this world.
Religion has done both it's fair share of bad and it's fair share of good in the world.
If you think athiesm would stop mindless killing then i believe you are severely mistaken.
Ok then it wouldn't be in the form of Isis etc but all over the world you see just as much barbarism where religion has no influence.
