But shouldn't we be bombarded with their signals? Floating relics of their space-craft or space-trash? Something? Anything? We haven't even discovered micro-organisms from outside of Earth, let alone complex multicellular spacemen.
It's eerie.

1. The universe is really really big. It's unlikely, no matter how successful the species, that we'd encounter tons of their space junk this close to us.
2. We've only been paying attention for the last 50 or so years. A really short span given the scale of space-time. It's just a snapshot really. Would you say that because you woke up briefly at 3AM and didn't hear any other human for a five second span that therefore humanity must have gone extinct? No.
3. We may be bombarded by their signals but we haven't developed far enough to realize it. We could be like the inhabitants of some small undiscovered pacific archipelago. We communicate with neighboring tribes via smoke signals but assume no one else exists outside because we never see any really huge smoke signals on the horizon...completely oblivious to the radio broadcasts that bounce around and through us or the satellites floating above.
That said we have found some weird stuff even in the short time we've been paying attention Wow! Signal

It is possible that it is physically impossible to travel the distances required for contact in the lifespan of any sentient organism. There may be no way to do, no matter how technologically advanced a civilization becomes.
As far as we know, it is impossible to construct a square circle. It may just not be possible to travel the distances required.
