IS A WORLD WITHOUT RELIGION A BETTER WORLD???

what causes ppl to be moral is an instinct for group survival. not fear of god. most ppl dont even believe in your gods. so they arent worried about his wrath. we have criminal justice systems because an imaginary god is not gonna keep ppl from breaking the law. with 2 million ppl in american prisons and 76% of the christian, that should be obvious. would the gaza strip be a better place to live without religion? hell yea
