Well even leaving aside the incomprehensible size of the verse itself, the Milky Way is quite a big galaxy with many stars and many more planets orbiting those stars. We also know that life exists on at least one of those planets and there does not appear to be anything profoundly special about that occurrence. Nor does the emergence of intelligence on our scale, pretty rare but not particularly requiring of incredibly special circumstances. Therefore the chances of us being alone either as the sole instance of life or intelligent life in the galaxy seem rather small to the point of being incredibly unlikely. The circumstances do seem to be specific enough to result in us not tripping up over alien civilisations every few star systems as Trek or Wars would have it. However, as we currently lack any actual concrete evidence for life, intelligent or otherwise, elsewhere in the galaxy then we cannot conclude that it is definitely out there.

I know it is a bit of a bold statement but some one has to be, maybe the reason E.T has not been in touch is that they can't and may not have the technology.
It is technically possible but I'd reckon it is unlikely, the galaxy has been around for quite a considerable time before humans ever appeared and our technical capability has barely arrived. It's really been less than one piffling century that we can scan the EM spectrum and broadcast over it. ET may well have aimed its equipment our way when there was neither anything to receive or transmit on this world and we don't have to travel far back to get to that situation. It is also possible that ET is largely doing what we currently do, listening without any deliberate broadcasting and like us so far have not encountered much; we did have that Wow signal event but that's still inexplicable and a sole event. Even our non-deliberate broadcast bubble is incredibly small in astronomical terms and the further out you get the weaker the signals become so that even well before the leading edge it would be indistinguishable from all the other noise.
That we've heard nothing is insufficient reason to suppose that silence should indicate we are the most advanced.

Possibly but really, really unlikely. As it is, the Voyagers and Pioneers are not aimed anywhere in particular and are really just adrift in the vast void between systems. Voyager One for example, in about 40k years it will only pass AC+79 3888 in the Ophiuchus constellation somewhere between one and two light years distance (as per Wiki). A teeny, completely dead probe will skip by in the vast void where it is unlikely to encounter anything or be noticed even were there anything there to notice. Even if any of the probes somehow managed to be captured by a system gravitationally and somehow then make it unmolested to a deteriorating orbit about an inhabited planet, the frail remnants will incinerate on the way down with little or nothing making it to the ground where the odds of it being found are astronomically slim at best. They will also only last so long before sustained micrometeorite impacts render them so much debris and that's their more probable future than being found by another intelligence.
I'm sure other places have had Roswell style events though, whenever the local government needed to hide sensitive activities by invoking a currently popular urban legend
Hope is but the first step upon the road to disappointment.
