I did not make the claim that there is no god. I merely pointed out that if the god of the Bible exists, then I have a higher moral standing - especially based on our idea of individual liberty and nonagression principles.
As far as any existence of a deity, it is up to the person making the claim of existence to demonstrate that existence. Not my job to prove a negative, for that is impossible to do. Go ahead and try it - prove the purple dragon who talks like Groucho Marx and lives in my underwear doesn't exist.
You are welcome to make the case that killing innocent children or owning another human being is moral and follows the principles of liberty. I think it would be nearly impossible....but feel free to try. It would be an interesting read at least. Again, it is not my job to explain basic human rights or the principles of freedom to you. Read John Locke and Thomas Paine.
And, before you say it again - the idea of "laws" are an abstract concept, yet physicalized in their codification after writing was devoloped. All of these "laws" are based on social axioms developed over tens of thousands of years as our species congregated in larger groups in combination with natural instincts and genetic markers of behavior.
"In the beginning of a change the patriot is a scarce man, and brave, and hated and scorned. When his cause succeeds, the timid join him, for then it costs nothing to be a patriot."--Mark Twain
