What this shows is the arrogance of man. Man is so arrogant that he forms fabricated ideas ideas in his own mind and thinks that because of his alleged "superior intellect regarding everything in the Universe" that all of his fabricated ideas are equal to the truth.

Then we he finds out they are not, it is described as "miraculous" because he was wrong.

Really, it's not miraculous. It's simply the truth coming out from time to time and showing that man's intellect is not anywhere so accurate as he pompously believes it to be.
