I have faith in some higher being if only because it makes sense, scientifically speaking.
Compared to, for example, micro-organisms - we are huge godly beings capable of manipulating everything about their living world. We can create, we can destroy, we can alter, etc. Granted, they don't know this because they're not exactly sentient, but..
What's so silly about believing that we are merely micro-organisms to some huge floating sentient gas-entity that is the size of several galaxies, or something?
I don't believe in God in the classical view, but I do have faith in something. I just don't know what. Life's too short not to believe in something.
ed- And I hope to fuck there's some awesome afterlife, because shit, I can't even begin to comprehend not existing.
