What would you change?

If I truly believed that there was no God, then there would be no purpose behind living at all. If nothing created us then there is no such thing as right or wrong, there is no such thing as love or hate. If there is no human soul, then emotions are nothing more than a series of random, unreasonable neural transmissions with no real weight or relevance attached to their existance. If we weren't created by something, then we are an accident. If we are an accident, then there's no reason why I shouldn't stop typing right this second and delete the most annoying accidents I've encountered recently. Example: I'm at work, and a man in one of our rooms just called down to the front desk and asked for a wake up call. When I answered the phone, he referred to me as "ma'am." Now, if there is no God, then there is no real meaning to the ideas of "wrong" or "right". If God doesn't exist, then those polar extremes are fabrications of the human collective unconscious, and they have no real meaning. If we're an accident, then so is everything we've created. That includes the ideas of wrong and right. So, what's stopping me from walking up to that man's room and killing him right this second? Because I know it's wrong. It may not be the Christian God that is looking down upon us, but something created us. If not, then what is the point of clinging to life in any way, shape or form?
