The Macroverse is literally everything, and everyone that is for eternity, and beyond. Probably what the average person would simply call the Universe. The Macroverse is made up of parallel Universes, Parallel Multiverses, Parallel Omniverses, a variety of parallel, and higher dimensions along with a plethora of Gods at various level who are ascended Afterlife beings such as humans. The Macroverse itself is the highest level God, and the only infinite God along with being the only true 100% non-corporeal pure thought being in existence. Everything below it is Metaphysical Energy to some extent, not including the Physical Energy of Universes such as our own.
Mounting evidence indicates it came into existence via something similar to a bootstrap, or ontological paradox. However far more complex, and beyond the comprehension of our 3-D minds. Every infinite soul frequency, aka all of us, first spontaneously evolved from a sea of pure information thought waves. These individual spirits, that can be called Vice-Macroverse Gods, then simultaneously, and spontaneously created a Neural Network that became the Macroverse God. Simultaneously to this creation the Macroverse God created the sea of pure information. Read The Rest Of This Recently Updated Article On Our Main Website…

Technically all of us were first. Every soul frequency came into existence at the same time, and instantly coalesced into the Macroverse God. We simultaneously exist independently, and collectively as one God.
