Two of my favorite explanations for the fermi paradox:
a) The space of possible ways to perceive the universe is far larger than we can imagine. If this is true, the good scenario is that we never see each other. The bad scenario is that they can perceive us, but we can't perceive them. ('Perceive' could mean 'detect', or 'have an optimized visual cortex to recognize'.)
But I suspect the most likely reason is just that they've all learned to be silent. Not because there's an uber-predator, but just because that's the nash equilibrium.
