Theists: What is the most compelling argument you have heard for Atheism?

[Brian37]

How about you consider that your naked assertion is merely a reflection of your own human qualities?...

Xenophanes "But if cattle and horses and lions had hands
or could paint with their hands and create works such as men do,
horses like horses and cattle like cattle
also would depict the gods' shapes and make their bodies
of such a sort as the form they themselves have.

You better stop before you beclown yourself any more, Brian. You're so ignorant that you apparently don't even know that Xenophanes was a monotheist and the above quote is a critique of ancient Greek polytheism. Idiot.

You assume I didn't know that. He's right about that analogy but again, being right about that would still not make his god real either. Otherwise since Arabs invented algebra, by that logic Allah must be the one true God. I was agreeing with his analogy, not any god claim he had.

My mom was Catholic, so by your logic, since I loved her, and knew her for 44 years, and since she got some things right, like teaching for 30 years, that must mean eating a magic cracker will save one's soul? Sam Harris is a neurologist, so by your logic, since he is into Buddhism, better convert to Buddhism. 

I don't care he was a monotheist, other smart people in history come from all sorts of religions and? Again being right about some things, does not prove any god to be real. 

You look at the world's religious artwork, funny how the spirits/deities/gods/prophets depicted reflect the societies they are created in. That is the same thing he meant. You look at depictions of Jesus in Italy he is more depicted in their history as having Italian features. Look at depictions of Jesus in Mexico or South America and they tend to reflect Latino/Hispanic features. Look at how the gods of the Hindus in India are depicted and funny that, seem to have the features of those born in India.Look at Native American spirits and their features reflect Native Americans history.

 None of my argument was proving a monotheistic god or polytheistic god by quoting him.
