Case in point: The greatest, once-in-a-lifetime event that makes any player that can pull it off go down in baseball history is the shutout. The shutout is basically an entire game where absolutely nothing happens, not a single batter for the other team ever gets a hit.
(Also, because shutouts aren't a team effort. The pitcher, and to a lesser extent, the catcher, does everything.)
You're thinking of a perfect game, not a shut out. They absolutely are a team effort - there have been several examples of perfect games that were saved due to great plays by the defense, or lost due to bad defense. This is fully outside of the pitchers control.

You don't know what you're talking about
I would go as far as to say every no hitter/perfect game has an iconic defensive play to save it.
