So let's look at this: The Universe is estimated to be about 15,000,000,000 years old. Let's say, on a good run, an advanced civilization lasts 10,000 years before it collapses. That leaves a .0000006% chance that their radio waves would be hitting us. Now consider the fact that, on the low estimate, there are 200,000,000,000 stars in the Milky Way and we have a handful of radio telescopes checking in on just a few thousand of those stars, you start to see why we haven't found proof of anything.
