There is much more to every universe than what can be perceived by mortal creatures. My true form spans far beyond the mere four dimensions that humans are normally capable of comprehending, and of those parts of me that do exclusively exist in those spaces, only some give off signals that your senses can pick up. It's possible you were only seeing a small portion of your Genesis Frog, and in turn, your universe.

[ It only stands to reason that if this frog contained a universe, it would have to be just as complex as an angel in form, at minimum. ]
