This all hinges on the presupposition that our solar system is unique in its configuration and location in the galaxy.
We haven't surveyed nearly enough other planetary systems to have any real idea if our system is unique. We barely have the ability to even see systems like ours in the first place. There's so little data available that it's not reasonable to draw a conclusion either way.
