I am not an atheist neither am i affiliated with any religion, but you ask how can an antheist be morally guided if he does not appeal to a higer power and i answer: morals are nothin but laws  (laws in the sense of gravity for instance) that humans must abide by to live in social harmony with those around them. Morals are not subjective but objective. Morality would still be present with out a God. It would still be wrong to kill if there was no God. You frighten me in the sense that you say that if it werent for a god u wud be a wild baby killing money stealin heroin shooting adulterating animal.
