One question I wanted to ask Professor Tartar was the relative technological advancement of other potential life forms in the galaxy. For example, if humans discover extraterrestrial life first, is it safe to assume that that planet would have less technologically-developed life forms? Because if some other civilization was more advanced than us, wouldn’t they be the ones to reach Earth first and contact us, rather than vice versa? And is there any logical predictive way through which we can reason the likelihood that we are the most advanced life form in the galaxy?
