How to get rid of background noise?

I’m trying to get rid of background noise from a clip, and I’m starting to think it’s impossible.

That video seems to be all noise. If you’re trying to separate the different sounds in that video, that can’t be done.

Hmm, well I was able to get this far, but I’m having trouble making some parts louder and getting rid of the remnants of the noise.
