Proof of Existence: Tate Modern
"In a little church in Rome, between the Vatican and the Tiber, there is a Museum of Miracles. There, I saw the most extraordinary photography exhibition. It consisted entirely of photographic documents presented as proof of God's existence. It was a ... metaphor [for] what all photography exhibitions should be." Clemont Cheroux
I'm not convinced of the existence of God. Thankfully though, there is photography.
