Let's say they exist. Greys, reptilians, all that. Can humans inflict fear in them? This fear doesn't come through pain though, and there's no torture involved. It comes from our REPUTATION of being excellent survivors and having the brainpower to think up and create all the tools needed to counter everything they can throw at us. Abductions are no longer a thing. Also let's pretend the government switches side and stands with the people. Will aliens begin to FEAR us to the point where they pee themselves by just the sight of a human being?
