A moment please Lauren?
One could argue, as indeed you have, that everything is everything.
I'd posit that since matter is made up mostly of the space between tiny atomic particles that everything is as close to nothing as makes no odds.
A very small number (representing the volume occupied by the sum of all of the atoms in the universe (this one, for the sake of discussion)) divided by a very large number (representing the volume of empty space in the current universe) is so near to zero that you can ignore it for all practical purposes.
In cosmic terms; everything is, to all intents and purposes, nothing (much).
