Me and Gypsy did this as a colab project together. The saying comes from the concept that at one time before the Big Bang. there was just one thing, but the Big Bang created the universe and everything we know of today. all the elements, all of everything, even your computer you are using right now could not have been made if it was not for our universe.
so thats where the saying comes into play, "Anything And Everything Are Both The Same"
