[two simultaneous, different conversations] John, Alien Visitor:
I'll try to put this in terms that you commonly use. I'm a scientist. We were all scientists. We came here to learn about your world. Our idea was to find out everything: your history, your biology, everything. We came here to learn. We're not that different from you, genetically, biologically. But what you call evolution has changed us. We see things in you that we no longer recognize in ourselves.
