If God does not exist, who sets the standard for what is “right” and “wrong”?

Does it really matter whether or not God exists? What about that age-old question of evil? Does the presence of evil really negate the reality of a God?

Are you serious? People are smart enough to understand right from wrong all on our own.
Oh, and if someone tries to tell you that people can’t figure out right from wrong then how would they know what these gods or god says is right or wrong?

But, if there is no God, how is it that there is good or bad? It’s inherent that humans have a sense of right and wrong, but why is that a thing?
