Seems like a non-sequeter to me. The inability to postulate a model or law to explain a phenomenon doesn't automatically lead to an intelligence that can. Indeed that seems to simply push the problem behind a curtain, the problem you describe is one of self knowledge (?) if you truly knew who and what you were you would, by definition, also need to comprehend your context (since nothing exists atomically alone.) The ability to know yourself to this infinite level does not in and of itself require a being who does (the ant does not require a human simply because a human is smarter.) What you seem to be arguing is the medieval concept of a chain of being with all creation in a heirarchy leading from rocks to animals to humans to angels to god.
The ability to imagine the impossible does not mean the impossible exists. Let me give you a bodged mathematical solution to your edge of the universe problem which is one of dimensional folding. Each dimension can be folded through the dimension above it (as a rough example a 2d sheet of paper can be folded into a tube or more interestingly into a mobius strip) , this folding does not alter its dimension but it alters the coordinate system (and in the mobius strip example shows how - at least in one direction - an edge can be removed and infinity produced) a better shape to demonstrate this is the torus which is infinite in any direction. Interestingly dropping down two dimensions produces a coordinate singularity (a dot!) while going up one dimension produces time (change within the current dimension.) At no stage does my ropey model require a superior intelligence to make it work.
