Louis C.K. on atheism

"I'm not religious. I don't know if there's a God. That's all I can say honestly is 'I don't know.' Some people think that they know that there isn't. That's a weird thing to think you can know:

 'Yeah, there's no God.'
 'Are you sure?'
 'Yeah, no, there's no God.'
 'How do you know?'
 'Because I didn't see him.'

There's a vast universe. You can see for about a hundred yards when there's not a building in the way. How could you possibly...Did you look everywhere? Did you look in the downstairs bathroom? Where are you looking? 'No, I didn't see him yet.' Well, I haven't seen Twelve Years a Slave yet, it doesn't mean it doesn't exist. "
