Effectively, we're the same as gorillas and ants on the cosmic scale, so this is not a good analogy. Humans communicating with amoeba would be a better one. But even so, we're not establishing diplomatic embassies and trade agreements with ants and gorillas. People keep thinking that just because we study ants and gorillas, that means my argument is spurious. Alien races that see us may find us intriguing, but Douglas Adams did explain this sort of stuff in fantastic ways, for example, when humanity missed the Dolphins' last message to Earth and interpreted it as a really neat triple somersault. So, yes, maybe gorillas and ants and dolphins are trying to speak with us, but we're not trying to have those conversations. We're having the "Do you want a banana?" conversations. What people think of when they think of UFOs is diplomatic relations between two cultures. And I am saying that, cosmically, we could no less have a diplomatic relationship between a human society and a cosmically traveling giant brain society than could a person establish diplomatic ties with an oyster. The frames of reference are simply not there to even communicate in a meaningful, cultural way beyond Pearls. So, maybe I am wrong and the giant brains are reaching out and do want to talk to us, but maybe they speak with asteroids and quarks and we cannot even begin to understand what they want. We're too busy deciding which ant is the correct, one true ant to lead us all.
