amazing, since you are quite knowledgeable, how do we define an alien invasion? 
1_Wizard
it's simply aliens invade the Earth either to exterminate human life or harvest people for food, steal the planet's resourses

When did this word ever come into play? have there been any sightings? or it's just a figment of someone's imagination

Alien invasion was a common metaphor in US science fiction during the Cold War

Do you think Hollywood might have blown the whole idea of alien invasion out of proportion?

I don't think so. i think a lot of people like the idea of aliens contacting Earth and observing it either to invade or sometimes help humans
