I think atheist who are convinced that no God exists, are as naïve as religious folks. I think we need to redefine what God is. I believe, if there is no God, then, there is only determination and Darwinism that rules the world. That means if you decide something is GOOD or something is BAD, it is only because either you got it taught this way (a lot of people don't question the fact that laws are good, never bad); or it comes from own experiences, through empathy (It hurted me, so I won't do it to you), empathy which, with other things in your brain where developed for the Human kind to survive as a population (Darwin). I believe, if you believe in God, you believe that there is something else, other than these concepts, that tells you what is right and what is wrong.
