did morality exist before the ten commandments?

I want to know what you think about the concept of morality. I've listened to some NPR podcasts recently, read about it some in this book I'm reading, and also, I found something in my journal about it. So now I'm wondering, is morality a concept that stands alone. Is it a self supporting independent "thing" that exists without the application of it's value in humanity, does it exist strictly with God? Or is "morality" a term we give to our own decisions and actions? It is it something that we manipulate, is it circumstantial? I had a conversation with Rob recently, about it. I think, in social context, morality is questionable. It's social organization, is it merely a social construct, a tool? Morality is a broad term. My friend thinks that morality is not dependent on the human definition, the social definition, but rather...it exists with God. Therefor, even "base" morality would be a product of God's will and creation. Is there a difference between God's morality and a human morality? Sure, the reason for practicing such morality would be different, but the daily application could be very similar. I think that people are strange. There are those who are very utilitarian, and morality for them is nothing but a tool, or a means to an end. There are those who can only have faith in a deity who's morality is perfection, and can't be tarnished or ruined...those hopeful religious types. There are those who have that pragmatic approach to morality, a "general morality"..and eye for an eye type of thing. All of these ideas lead to my idea that "morality" is merely a construct of our own. It's something we make perhaps. I wonder how the ten commandments changed the idea of morality? Before God's law, was there only moral anarchy? Was morality understood before the ten commandments, and did the ten commandments merely give these mysterious social parameters a name, a focus and a source. (perhaps my biblical history is off) I hope this post doesn't come off with an air of certainty. I've just been thinking about it a lot. I keep finding myself further away from believing that morality is a supreme concept, and unmoving ideal. If the application of morality is able to shift along with each new circumstance, can it be said that there is an unmoving and solid concept of morality at all? I'm not going to proofread this at all, I'm just going to post it. Everyone, correct me....lets' talk.
