It’s sort of fun to think about. Exoplanets do exist, so that ups the odds more of intelligences other than ours....Yes, yes, we being intelligent is purely speculative considering the evidence, but I see to much physics in the way for them to come here. Why even here? We are a noisy planet, but we’ve had radio for what? 200 years, so any life capable of receiving it and decided to check out the neighbors have to be within 200 light years. Then physics raises it’s ugly head again. I think if there are civilizations, we are separated for a reason.

At latest estimate of the 300,000,000-400,000,000 stars in our Galaxy alone, it is estimated that every star has at least one planet.
