My guess is that our universe is simply 1 among an infinite number of universes much like the stars are in a single universe.

Bingo.
Question; In all of nature (that we can observe) where is there only ONE of anything?

“Question; In all of nature (that we can observe) where is there only ONE of anything? ‘

That wouldn’t support the idea that there are multiple “natures”. An infinite expansion is just as much a logical fallacy as an infinite regression.
