What if Radio waves simply don't work the same on other planets .

Or one of the first things civilizations figure out is to not broadcast your presence.

Or ... Everyone else in the universe found peace by stopping at the stone age , before all this social media made us miserable.

It's just conjecture, but I imagine aliens exist, but they might not even be in a form re recognize.

Well, to pick some nits, if radio waves didn't work the same way, that would be a pretty fundamental shift in physics, to the point of throwing all our assumptions out the window about our observational evidence.

We're assuming they communicate the same way we would.

I'll make up something scifi like. On planet x they use short term Seismic wave to move data around. How would we on earth ever pick that up
