Where do atheists get their morality from?

Would you agree then that a conscious being able to create the universe, must necessarily have greater power and knowledge than that within the universe which would otherwise be or would be the most powerful and/or most knowledgable?

Nope. There is no justification for this.

This gives us a being of great power and intelligence; a independent being itself, which humans and all of existence are contingent upon (thus objective). This, to me at least, makes for (literally) a great authority. This was essentially what was meant from:

In examining those attributes then, wouldn't it be altogether rational to deem such an independent being as a viable authority in our lives?

Except, you are using the word "objective" incorrectly here and you simply have no idea what this being could be contingent upon.
