Generally many religious people argue that ethics and morality are based on what God commands them to be and fail to see that morality can still be just as meaningful to a person who does not believe in God. Theists, followers of God, assume that religion is a substantial reason for our moral conduct. Non-believers such as atheists are still able to understand the difference between right and wrong without religion. John, believes that if there was no higher power to give us established rules and reasons for how to behave, then everything we do would be measured equally. Andrea, on the other hand, who is against this theory, underlines that God is not the key to having moral values. His argument seems to be more convincing because an atheist can still do the right thing based on his own self-interest if he has a rational explanation for moral values. The only difference is that non-believers do not have a supreme ruler to measure the intensity of the moral standard of their actions. Doing the right or wrong thing should be justified on the level that your actions hurt or harm someone in any way...
