When it comes to thinking about first contact scenarios we tend to default to imagining humanity versus a more advanced alien race. Typically this comes in the form of massive spaceships orbiting the earth, hovering above our cities and counting down the hours until they attack. It’s the Independence Day scenario, or more recently Arrival, a film that gives this trope a new, more conscientious spin. In Arrival the Septopods arrive on Earth, and it is us who are on the brink of hostility towards them, rather than them being a clear threat to us. In the film Avatar, it is us who are the more advanced race, and while we don’t see our first contact scenario with the Navi, it is this angle that I want to explore; human supremacy over the other; a scenario that we have actual evidence to draw from.
Imagine, no matter how unlikely, that we receive a message from space. One that we’re able to translate, or maybe one that is—possibly more concerning—already translated for us. The message simply reads;
The ground shuddered with each and every impact of the morning's bombardment. The number of shells hitting the enemy line was so immense that each thud merged with the next, each crack of the detonations became one endless sound. The wet mud of the trenches vibrated, the ripples hitting one another, loosening the caked walls of the trench.
Like all stories that are worth telling, this one is true. Granted, an absurdity, as you will soon come to see; a true story that cannot possibly be, yet one that I have a first-hand account of. My own first-hand account. Twice, so far.
Alien invasions of Earth have been a staple of science fiction storytelling since H.G. Wells. From then to today we have had stories of humanity versus an alien threat retold to us in many different ways. Many of us have almost always enjoyed these forays into human nature, but sometimes there is just something missing. There are occasions when the writers display a lack of thought into the science behind alien motivations in favour of a romp through science-fiction tropes, but to some of us—myself included—the science behind the whys and wherefores are just as important as the narrative on the whole.One of the most common reasons we see in fiction for aliens invading the Earth is territory; the act of taking our home world for themselves, wiping out us pesky natives in the process. On the surface, this seems to be a logical reason for the launching of an invasion and a believable one. Let's put aside the idea of using science-fiction as an analogue to explore real issues for a moment, and we can see this concept start to unravel. How? It comes down simply to the level of technology these aliens can employ. They're putting together an invasion force, and constructing the machines and/or equipment needed to do so. They also must have ships that are capable of transporting an entire population insanely long distances. Clearly, if they can put the resources into something like this and have the tech available to sustain themselves on such a journey, why would they not look at the prospect of space habitats? Is there a particular reason that they're unable to colonise a slightly less suitable world such as we are planning to do onMars.It would be far less effort for them to construct their own colonies in space or on worlds where the natives won't be a problem.
