As a first approximation: yes. Nobody can pull it down because not even the tallest human is tall enough to reach it. By far. So that is the answer to that.
On the other hand I assume you mean: Is it possible to pull it down with some machine? And the answer is yes, it is possible to pull it down with some machine.
Entirely within the demonstrated abilities of humankind.
If we want to, have enough money and time, we could make a machine which captures it, takes it to Mars, lands it there softly, dances the cha-cha-cha with it there, launches again back to Earth and lands it softly here. Entirely possible. Only a matter of time and money.
It is not a question of impossibility. It is a question of how much time you have (remember it is drifting out of your airspace) and how much money you want to spend on it, and how certain you want to do it, and how safe you want to keep your personal and people on the ground while doing it.
