I want Him/Her to exist because then it would be easy to blame a lot of stuff but the matter of fact is that He/She can logically not exist and even if It does, the odds of us doing it wrong and thus invoking his wrath anyway are against us. There are and have been thousands of religions and they all say that if you're not doing it right, God or gods will destroy you (or punish you).
You cannot limit yourselves to the Biblical god either because the Bible is full of contradictions and logical fallacies so you have to be accepting of any god or gods in order to be truly objective. The greeks had it right when they recorded their philosophical tragedies - gods are hard to please and doing what one god wants may upset another one so why bother pleasing a God or body of gods (the Godderning Body ) that can never be satisfied (as symbolized by the unlimited sacrifices of the Jews/Israelites) if you can just as well make your way yourself in love and fine works?
The biblical God is a contradiction in itself. You cannot be perfect in love and be all-powerful yet allow suffering. The omni's assigned to the being (omniscient, omnipotent,...) are logical fallacies in themselves since you are not omnipotent if you can't can't do something, you can't be omniscient and account for free will.
It's safer for us as a society to not be able to blame something else for our own shortcomings and thus we should concentrate on bettering ourselves instead of leaving it up to a supernatural being. Whether you need a God for that is up to you but I think I'll do fine without. God is a nice concept as a parent when teaching a child - don't do wrong because something is watching over you and it has it's place in social structure. However we have all grown up now and don't have to be acting as children anymore, take responsibility and suffer the consequences.
