I always sort of vaguely wonder if we actually are surrounded by evidence of intelligent life, we just don't know how to interpret or even detect it. Sort of like one of those isolated Amazonian tribes surrounded by wifi signals.
I think it's either something like that, or we haven't found anything because the universe is just too big and there simply isn't any way to get around it, no matter how advanced a species becomes. Like FTL travel/wormholes/whatever just isn't possible. Which is not a fun explanation but Occam's Razor and all that.
Relevant xkcd to the first point.

My son is taking an astronomy course with a highly regarded astronomer, and she believes there are many, many intelligent civilizations in our galaxy alone. They are just too far apart. A galaxy may look small in an photo with lots of galaxies, but in reality, a single galaxy is so huge as to be almost mind-boggling in itself, without even considering the wider Universe.
