AANR/Theists: What is your opinion on this quote by Martin Amis?

"I'm an agnostic, which is the only rational position. It's not because I feel a God or think that anything resembling the b God of religion will turn up. But I think that atheism sounds like a proof of something, and it's incredibly evident that we are nowhere near intelligent enough to understand the universe.... Writers are above all individualists, and above all writing is freedom, so they will go off in all sorts of directions. I think it does apply to the debate about religion, in that it's a crabbed novelist who pulls the shutters down and says, there's no other thing. Don't use the word God: but something more intelligent than us... If we can't understand it, then it's formidable. And we understand very little." (Martin Amis, Prospect interview 2010)
