Let's say that science proves that God exists

[Esquilax]

As a human, I have this thing called empathy, which allows me to interface with the experiences of my fellow human beings. In having this ability- and since we're herd creatures evolution no doubt sharpened this sense in most of us- I am willing to allow other humans certain rights that I would like to have myself.

I'm glad you do arbritrarily feel that way. But your feelings don't have any basis in fact if humans are just the unintended by product of the laws of physics....your feelings not withstanding.

Couple of things: One, it's not arbitrary, it's an evolutionary instinct honed in the majority of mankind specifically to engender social health in the herd animal that is humanity.

And two, you asked where our rights came from, and I answered; first by showing you that it's ridiculous to think that we have any predefined rights at all- something you neglected to even acknowledge- and then by showing you where the desire for those rights developed in a universe without a god. And instead of actually responding you give me... what? A restatement of my original premise, as though that should count for anything when I was working within that framework to begin with?

If you don't have an answer that's fine, just don't pretend like you do.
