I personally think life is probably common in the universe. We've only been able to prove exoplanets exist within the last few decades, but the evidence is already that there are a number of planets that are hospitable to life (our kind at least). We've only just started scratching the surface and we've already found things like Tabby's Star [1].
Obviously I think there's a point to us trying to communicate with whatever is out there, I just think we shouldn't be surprised by the lack of response.
