If you consider the likelihood that some aliens are orders of magnitude larger than us, and some smaller.... maybe we don't register on each others' sensors.
The odds of meeting Klingons or Romulans..... 6 feet tall, bipedal, O2 breathers is almost laughable... I don't doubt that they're out there. I just doubt that we will meet them before we all get eaten by space monsters.

Another thing to think about is time scale. What about beings/civilizations that rise and fall in an instant and others that take one (figurative) breath every eon? Obviously we can't perceive those.
