The galaxy is populated, much like Earth. The power controlling our region has a policy of leaving us alone. End of story.
This requires no great filters or fantastic coincidences, and assumes galactic society is organized much like Earth.

Another theory that doesn't require a great filter: The distribution of life may not be equal across the galaxy if it's truly random, we could be in a local minima and never meet another civilisation by the bad luck of where we are.
Never thought of the practicalities of that, so thanks for bringing it up.
I think you're overstating things. Sure, they wouldn't be able to watch the Superbowl at the same time or hold elections in the same decade. It would be a very different and slow moving kind of civilization than what we know.
But I don't see how that means it can't exist, in some form.
Or perhaps the good luck of where we are

A more interesting answer is they are simply horrified or disgusted: look up "They're made out of meat!"
Is it that hard to believe that our local aliens ignore us for the most part, that sometimes we see their spacecraft and mistake them for natural phenomena, and when one of them approaches illegally if they land in the wrong place they just get killed?
Or they just don't care to visit our solar system because there's nothing of interest here. I'm sure you can imagine a 18th century European surveyor sailing past a bunch of new islands, noting them on charts and tossing in the description "contains no resources" and then moving on.
Or maybe they've come, but only in very small numbers. They radio home and leave for the next system to explore.
If we assume that an advanced civilization will develop machine intelligence on a large scale with efficient processors and vast energy resources, it's possible that they've already fully explored the nature of worlds such as ours, and they don't have any reason to monitor them further.
Even a slow moving star hopping civilization should have spread across the whole galaxy many times over by now.
The 18th century surveyor skipped some islands, sure. But by now they're all accounted for.
When has earth society ever successfully left something new and foreign alone?
If there is a 'galactic directive' to leave us alone, it's because we were seeded here. I.e. we are the aliens, and being observed as some sort of experiment
