let's see:
>there is life on Earth for almost 3.5 billion years
>the moment we turned from almost animals to humans was like 5000 years ago
>we can send and receive radio signals for like 100 years
I'm sorry. the dinosaurs derped around on earth for over 135'000'000 years and you are complaining that in those 100 years we weren0't visited yet? and we may only have one data point but human-like intelligence evolved only once(!) in over 3'500'000'000 years! what does this say about the likelihood of evolving such an intelligence?
