God is in each and every one of us and that is why you have morals and a conscience. you don't have to believe she exist! he believes in you.

Morals serve the social good and can be enforced by society to help ensure its survival, which in turn, helps ensure our survival.

To give these morals more authority, they are often said to have been authored by a god/dess or god/desses. However, we do not need this fiction to justify nor enforce these morals. They are largely internalized by each member of the society, so we carry with us a sense of right and wrong, even when out from under the supervision of society.

I don't believe in god, so god does not exist for me, yet I have morals.

Morals come with respect for yourself and others.

Yes, just as things can be morally right. The presence of a deity is mutually exclusive to the presence of morality. It is not necessary for one to be present to have the other. Rather, it's the point of philosophy to guide us in what is or isn't morally acceptable. Is it possible that God exists? Sure, there is a slim chance that some kind of paranormal being exists. However, that existence doesn't cause morality. It merely portrays, whether or not it exists, a personification of the moral values of the society where the deity is present. Therefore, society is the determining factor on morality, and not God.

If God did not exist, would humans still have a conscience?

If the answer is yet, then my answer is yes. The conscience is that which makes one realize good from bad, regardless of God.

It's called utilitarianism. I don't understand why I'm the only one on this site that seems to accept it. It seems so obvious to me that utility is the root of morality.
