If a space alien came to visit us here on earth, would they just think we were a bunch of ants? Yeah, well, it depends on how much smarter than us they were. It wouldn't take much more smarts to land there. The audacity of us to say, let's find other intelligent life forms like us. That is not invoking a cosmic perspective on what is possible. Consider that we defined just one little fact here. We measure the intelligence of other animals by their capacity to communicate with our tools,. Like the chimp using sign language.
