How to easily defeat any argument for God

[Belacqua]

In addition to categorising "good" as indefinable, Moore also emphasized that it is a non-natural property. This means that it cannot be empirically or scientifically tested or verified - it is not within the bounds of "natural science"."

-Wikipedia.

I completely agree with Moore here. And I think that the people arguing with you don't understand what's going on. 

Just by chance I found this last night on a philosopher's blog:

“Talk of moral ‘perception’, like talk of mathematical intuition, or of reference and understanding, is not reducible to the language or the world-picture of physics. That does not mean physics is ‘incomplete’. Physics can be ‘complete’–that is, complete for physical purposes. The completeness physics lacks is a completeness all particular theories, pictures, and discourses lack. For no theory or picture is complete for all purposes. If the irreducibility of ethics to physics shows that values are projections, then colors are also projections. So are the natural numbers. So, for that matter, is ‘the physical world’. But being a projection in this sense is not the same thing as being subjective.”

— Hilary Putnam, Professor Emeritus of Philosophy at Harvard

And in other news, we'd been expecting this typhoon for a week and hearing how dangerous it is, and it passed over last night without even a power outage. All my roof tiles are still intact. It's almost disappointing.
