(Adapted from something Matt Dillahunty said)

So, you don’t believe in God? 

Nope.  I don’t have enough evidence to believe in a god.

What will it take to convince you? 

I don’t know. 

If you don’t know what will convince you, how will you know when it happens? 

It doesn’t matter if I know what would convince me.  If your god is omniscient, he already knows what it would take to convince me, yet he hasn’t done it.
