“Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.”

Douglas Adams, The Hitchhiker’s Guide to the Galaxy (Hitchhiker’s Guide to the Galaxy, #1)

As others have said, there may be a ton of debris up there, but the chance you’ll actually hit something is very small because space is just that big.
