How can you estimate likelihood of behavior when currently N=0 (or N=1 if you count humans)?

There is no baseline, no control; it's just complete speculation, a roundabout way of saying "this is what I think humans would likely do, therefore, all advanced life forms must also be like this".

Projecting behavior onto a phantom is just a venue for reflecting a personal worldview onto something else. "Being short-sighted and selfish worked for the aliens, so it would work here too".
