What will happen when highly evolved aliens with super advanced technology find our little planet bulging with life and recourses? The alien invasion scenario has been a popular topic in science fiction since the beginning.
When aliens invade in movies, humans usually win. This is because of stupid aliens. In both War of the worlds Signs the aliens come to earth unprotected and is killed by germs and water. In Independence Day the aliens are smarter and wear a protective bio-suit, but still they are not smart enough to stop humans infiltrating their mother ship and uploading a virus to disable their shields.
How realistic is this scenario? Jeff Goldblum only needs a few hours to understand and create a virus for their software. They than proceed to take a 50 year old alien ship and flies into the mother ship. Does the aliens not have serial numbers on their ships? Do they not wonder why a 50 year old ship is entering the mother ship, do they not wonder why a small fighter class ship is flying into the mother ship, no other fighters come from earth. Do they allow any ship to upload information into the mainframe to be distributed fleet wide? Properly not…
The alien invasion movies of 2011 have shown a more realistic scenario, biomechanical invasion units. In Skyline the aliens collect humans so they can use our brains as computers in different kinds of collecting units, flying, walking and humanoid ones. In World invasion battle Los Angeles the aliens send biomechanical units to defeat our military. There is also a new alien invasion TV series airing right now, Falling skies. Here we see civilians and the remains of military personnel form a resistance and fight back. In the series the aliens use mechs, flying units and (spoiler) genetically altered aliens (soon human kids they harness will also transform) to collect crap metal to build their platform thingy with unknown function. The invading aliens themselves are laid back out of harms way.
It makes sense to use Biomechanical soldiers instead of your own kind. However, an alien race so advanced they can cross the stars would properly have an even better solution. In an article I read, someone said the most likely scenario of a alien invasion movie would be people getting sick, and then everyone dies, the last thing you would see in the movie would be the last person dying looking up at the sky seeing alien spacecrafts landing everywhere. This makes sense, why fight humans when you could simply kill them all with a virus you engineered.
This is my take on a likely scenario for an alien invasion: The aliens send billions of flying Nano-bots into the atmosphere. The Nano-bots infect all humans and concentrate in our brains. The humans can then kill us all of simultaneously or tell us that we are their slaves and must do what they say or else we die, probably demonstrate this by killing all army personnel or something like that. And if the Nano-bots were advanced enough they might just control us directly right away.
Only reason they would come down to fight us, would be if they have lost their planet and have been drifting through space with little recourses, like in the movie Battle for Terra, this is a reversed scenario do, worth checking out.
In conclusion, if aliens come with the intent of taking our planet they will succeed. Whey will not forget to inoculate themselves against human deceases, they will wear protective suits if they melt in contact with water, they will have safeguards in their software to prevent humans made viruses and most importantly they would probably kill or enslave us all without even showing up on earth. To use the words of C-3PO – we are doomed!
