Nothing.

I can't see anything. There's nothing to see because there's no light with which to see. I look around and there's only infinite, pure darkness.

No light.

Interestingly, even though I experience and know nothing from a physical standpoint, I rationally acknowledge the possibility that there are many things near me, and that I still and ultimately experience, from a cognitive standpoint.

Schrodinger's Cat.

Both nothing and something(s) exist, by virtue of the darkness.
