When Aliens Invade The Best, Worst, And Most Likely Scenario

alien_invasion_600

It’s a common, but appealing theme in science fiction. One day, we think we’re alone in the universe. The next, aliens invade and our species is never the same. Whether it sparks a war for survival like in “Independence Day” or leads to a new era of inter-stellar cooperation like in “Mass Effect,” it’s a profound moment. It may be the one case in which our collective imagination is too limited to appreciate the implications.

The concept of first contact is daunting enough. Just discovering extraterrestrial life in the universe would be groundbreaking. Making contact with it would be downright overwhelming for our species. It might be the closest thing human beings ever get to a true religious experience, making contact with another species from the stars.

An invasion, however, carries with it a special kind of impact, albeit a traumatic kind. Science fiction tells all sorts of stories about it, but chances are that the real-world possibilities don’t come close to the fantasy we all envision. Whether it’s triumph after a stirring speech from President Whitmore or doom at the hands of Martian invaders, the truth probably somewhere in between.

I’ve argued before that the human race isn’t ready for contact with aliens, but we’re close. I also believe that if extraterrestrial aliens ever do arrive, they won’t be hostile invaders. If they’re advanced enough to travel the vast distance of the cosmos, then they’re advanced enough to not need anything here on Earth. There’s abundant water, minerals, and rare elements throughout space that are fare easier to obtain.

However, that all assumes that an extraterrestrial species would act in accord with incentives that most humans understand. That could be a flawed assumption. If an extraterrestrial species is truly alien, then their thoughts, feelings, and motivations could be alien too. It’s not impossible that a species would evolve to be inherently hostile to any other sentient life.

With that in mind, I’d like to present a few potential scenarios on how an alien invasion would play out for humanity. I believe there are a few instances in which our species would survive and even be stronger. There are also a few in which our hopes of survival are effectively zero. I don’t claim that any of these are definitive. This is just my attempt to speculate on how an invasion would pan out for humanity.


Worst Case Scenario: Aliens See Humans As Cockroaches

This is the scenario that movies like “Independence Day” or “Predator” often utilize. The invading aliens are advanced, capable of technology that traverses interstellar space with ease. They arrive on Earth, seeing its resources as ripe for the taking. They invade, seeing humans as nothing more than annoying insects. They deal with them the same way we deal with ants.

While those movies often build stories around human beings finding a way to win the day, either by discovering a hidden weakness or somehow hacking alien computers, it’s doubtful that this is how it would play out. If an alien species is hostile and they have access to technology so advanced that it might as well be magic to lesser species, then we have no chance.

In this scenario, there’s nothing humanity can do to fight back. The President Whitmores of the world could give all the inspiring speeches they want. We wouldn’t have a chance against these creatures. We would be like mosquitoes trying to stop an oncoming nuclear missile. We wouldn’t have a chance and at most, we would just annoy the aliens.

In some cases, humanity could survive by simply avoiding the aliens and live underground in hopes that they’ll eventually leave. If the invaders are intent on turning Earth into a base or strip-mining it entirely, then that’s just delaying the inevitable.

In other cases, the invading aliens could see humanity as lab rats or pets. The only reason they would keep some humans alive would be as resources. On many levels, it would be even worse than slavery because the aliens wouldn’t even value anything we could do. They would just value our flesh the same way we might value a mineral.

One way or another, humans don’t survive this invasion. We either get wiped out with ease or turned into glorified pets for aliens. It’s the one alien contact scenario we would want to avoid and one that the late Stephen Hawking dreaded the most. While I think it’s unlikely that we’ll encounter intelligent aliens this hostile, I don’t deny that it’s still a frightening possibility.


Best Case Scenario: Inept And Incompetent Invaders

This is something a lot of common sci-fi tropes rely on. You have a race of aliens advanced enough to master inter-stellar travel, but incompetent enough to lose a war against a bunch of hairless apes who kill each other over what they think happens when they die. Essentially, any story in which humanity defeats invading aliens has to rely on this.

While there are plenty of absurdities inherent in those stories, it’s not impossible to imagine an invading alien race that’s incompetent. We assume that any advanced alien race that can travel across interstellar space has to be competent to some extent. However, just because they can travel across the stars doesn’t mean they’ll be effective invaders.

The best example of this, in my opinion, comes from a series of novels by Harry Turtledove entitled “Worldwar.” In the story, an alien race invades Earth in the middle of World War II. However, the aliens in this story aren’t some unkillable monstrosities like the Xenomorphs. They’re a race of reptilian creatures who just made some false assumptions.

In the novels, which I highly recommend, the aliens advance at a much slower pace than humanity. What takes us 100 years to produce technologically takes them 1,000. When they first observed Earth, we were in medieval times. They assumed that humans advanced at a similar rate and would be push-overs by the time their fleet arrived. They were dead wrong.

If humanity ever has to deal with an alien invasion, these are the kinds of invaders we should hope for. It’s not just that they make false assumptions and grossly underestimate other species. An invasion by inept aliens means humanity has a fighting chance.

While it may still make for a bloody and brutal war, like the one that unfolds in the “Worldwar” series, that war may ultimately unite the human race in ways that would not be possible in any other scenario. Former President Ronald Reagan even pointed this out in a famous speech to the UN and I think he’s right.

Humanity has never had a singular existential threat that would require every race, ethnic group, and nation to unite. For our entire history, we’ve never had to deal with an advanced species trying to wipe us out. Having that threat means we have to work together or die. No matter how much humans disagree over trivial things, survival tends to overrule petty grievances.

In the long run, that kind of unity might help the human race come together in a way we can’t imagine, given our current state of disunity. As bad as a war against alien invaders can be, it could bring out the best in us if we have a fighting chance. Unfortunately, that chance is contingent on the invaders being incompetent and I think that’s hoping for too much.


Most Likely Scenario: Aliens Invaders Are Indifferent To Humanity

Of all the invasion scenarios, both in fiction and those with a passing connection to reality, I think this is the most likely. Again, it assumes that invading aliens are competent enough to get what they want, regardless of whether or not the human race wants it. If their technology is sufficiently advanced, it won’t matter what humanity wants.

However, that doesn’t necessarily mean that aliens see humans as bugs that need exterminating. It’s far more likely that they’ll see humans the same way drivers see an ant hill on the side of a major highway. They’ll barely notice. They might not even realize we’re there and we, in turn, might be completely oblivious to them.

Even if Earth has some resource that invading aliens want, it makes more sense to just take it without humans noticing. That way they don’t have to fight a war. It’s not that they couldn’t win that war with ease. It would just be exceedingly inconvenient. It would be like blowing up a dam just to water your garden.

For all we know, this has already happened. There may have been multiple occasions where intelligent aliens have passed by our planet, dropped in, and taken some resources without anyone knowing. Given how humans have only existed on this planet for a small fraction of its history, it’s entirely possible that advanced aliens have already visited and determined there’s nothing worth seeing.

Even if they did arrive at a time when humans were present, they would be plenty advanced to either evade detection or fool anyone they came across. The human brain is easy to trick, especially if aliens have some sort of cloaking technology or can shape-shift like the Skrulls in Marvel Comics. Deceiving people, even in today’s connected world, wouldn’t be too tricky for them.

If the aliens just want something minor that doesn’t require exterminating all life on Earth, it makes more sense to just slip in and take it. The only reason invading aliens would ever be hostile in this scenario is if humans got in their way or created an obstacle, of sorts. In that case, it wouldn’t entirely be the fault of the aliens for attacking.

I think this is most likely because I believe, in our current form, humans haven’t done enough to really make themselves worthy of contact with intelligent aliens. Sure, we have a space program and we’ve created world-ending technology, but we haven’t shown an ability to affect much beyond our own planet. I think until that changes, any advanced alien civilization wouldn’t have much interest in us.

That’s still assumes a lot about the intentions of advanced alien life, which can certainly be wrong. However, until we actually meet alien life, we won’t know what to expect. There are plenty of possibilities in which such contact would benefit the human race immensely, but there are far more possibilities in which that event goes horribly wrong.

Is The Human Race Ready For Contact With Alien Life?

contactparty

In general, I tend to have a high opinion of the human race. I believe that, in general, people are inherently good and will do the right thing in the long run, even if it requires mistakes and missteps along the way. Some of my personal experiences have fed this belief, as well as stories of incredible acts of compassion.

I say that as a preface because my faith in humanity does have limits. There are certain issues where those limits become a critical factor in answering major questions about where we are, as a species, and where we’re heading. I’ve tried answering some of those questions before, such as humanity’s readiness for advanced artificial intelligence. Now, I want to try to answer another where I feel humanity’s limits are a real issue.

It has to do with whether or not humans are alone in the universe. It’s probably one of the most fundamental questions our species has ever asked, inspiring heated debates, famous equations, and Hollywood blockbusters. I’ve certainly asked that question a time or two when looking up at the stars. I imagine there are few people who haven’t.

At the moment, the sheer size of the universe and the ever-growing number of planets we keep finding, the raw numbers make it almost certain that there’s other life outside our planet. It may even be within our own solar system. Just finding some microbes on one of Jupiter’s moons would be pretty profound, but I doubt it would bring that much change to the human race. Some might just brush it off or call it fake news.

It’s the act of discovering intelligent extraterrestrial life that has far greater implications for humanity. I would even argue that those implications could determine whether the human race will survive beyond the destruction of Earth, which is inevitable. Even advanced artificial intelligence wouldn’t compare because at least humans would create that. An intelligent alien civilization would be much less predictable.

In confronting this existential issue, I don’t believe movies or TV shows have come close to getting it right. “Contact” made a commendable effort, but never gave more than a half-answer. Movies like “Independence Day” and “Close Encounters of the Third Kind” were overly simplistic in their approach. That’s to be expected because, logistically speaking, there’s no way to fit all the implications into a single two-hour movie.

I believe that to answer the question of humanity’s readiness to confront an extraterrestrial species is multi-faceted. There are plenty of factors to consider, but before I get too bogged down by the particulars, I want to offer my personal opinion on the issue. Then, I hope to demonstrate why I have this opinion.

No, the human race is NOT ready for contact with intelligent extraterrestrial aliens, but we’re getting there.

I know that isn’t a straightforward answer. It may sound like I’m trying to stand on both sides of the fence, but like I said, the question is inherently complex. As such, it’s hard to offer a simple answer.

Part of the complexity comes from circumstances. In an instance where scientists on Earth identify an advanced alien species, possibly by detecting an alien mega structure like a Dyson Sphere around a distant star, I think the human race could handle that, for the most part.

Such a discovery would be, by far, the greatest ever made in the history of humanity. It would be the story of the millennium and confirm, once and for all, the answer to one of the most fundamental questions our species has ever asked. Getting an answer to that question would change how we see ourselves in the universe, but the extent of the impact would be limited.

Sure, it might cause some disruptions with respect to major religions, although some denominations already preparing for that. It might also cause some ripples in the social fabric of society. If we know there are alien civilizations in the universe that are more advanced than us, then suddenly we have fewer excuses to impose petty divisions within our own species.

There would be upheaval. There would be tension, as well. I still believe that society would adapt in that scenario. Once the shock wears off, we may very well go back to how we were before. Future generations would just shrug off the notion that advanced aliens exist and focus primarily on the issues directly affecting them on Earth.

There’s another instance, however, that has far more profound implications, as well as greater danger. In that scenario, the advanced alien civilization contacts us directly. Moreover, it effectively announces that it’s coming to meet us and there’s nothing we can do to stop it.

In that scenario, I don’t think the current order will remain intact. If we found out tomorrow that intelligent aliens exist and they’re on their way to greet us, I believe that society, as we know it, will fall apart under the weight of fear, uncertainty, and outright dread.

My reasons for believing this have less to do with my faith in humanity and more to do with my understanding of basic human psychology. It’s proven science that the human psyche is adverse to uncertainty. From a purely survival standpoint, that makes sense. Not knowing whether there’s a hungry lion hiding in the bushes is detrimental to our survival. We have a legitimate evolutionary reason for avoiding such situations.

An advanced alien civilization isn’t just a possible threat. It’s the ultimate uncertainty. Even if those aliens are peace-loving hippies who want nothing more than to create a utopian world for every species they encounter, we won’t know for certain. Even if they try to articulate their peaceful intentions, we may not believe them because assuming wrong would be more dire than any hungry lion.

If an alien civilization is advanced enough to both contact us and traverse interstellar space, then it’s highly likely that we wouldn’t stand a chance at stopping them. Despite what “Independence Day” might have you believe, there’s just no way we would be able to counter technology that could carry another species across the stars.

On top of that, we wouldn’t even know if these aliens were biological creatures, like us. More than a few scientists have speculated that it’s the natural path of all advanced life that it transcend its biology to become machines in part or entirely, which makes sense for any species that wants to survive in the vacuum of space. I would agree that any initial encounter humans have with advanced aliens will come in the form of a probe.

Even if that probe is no bigger than a basketball, its arrival on Earth would trigger so much panic that our society, economy, and political institutions wouldn’t survive in their current form. That’s not to say civilization would completely collapse. Some areas might descend into anarchy, but most wealthy countries would remain intact.

However, I believe they’ll remain intact through strict martial law. I also believe that, in the face of incoming aliens, there would be a huge scramble among nations to put together some sort of defense plan. Anyone remotely experienced with science or engineering would suddenly become incredibly valuable for their skills and likely be required to work on this issue.

No matter what recourse humanity takes, though, I don’t think it’ll matter once intelligent aliens arrive. The worst case scenario is that people are so afraid that a few become too trigger happy and attempt to attack. In that case, if the advanced aliens are the vindictive type, they would probably wipe humanity out with the same ease that we would use to step on an ant.

While I don’t think that scenario is that likely, I can certainly see fear dominating the discourse. It would probably extend beyond the initial contact. Even if  the aliens present themselves as friendly visitors, I imagine there will still be plenty of paranoia that it could all be a trick. Given how eager some people are to embrace conspiracy theories, I think this will cause plenty of problem, even in the best case scenario.

There’s still a chance that the human race could adapt to this encounter and be stronger because of it. However, if I had to bet money on the ultimate outcome, I wouldn’t wager much on that outcome. I think, at the moment, it’s more likely that fear and uncertainty will lead to the kind of irrational behavior that would prevent humanity from benefiting from an encounter with intelligent aliens.

As it stands, humans can’t even prevent conflict when encountering one another, especially if they look and act differently. I can’t imagine it would be much better if we encountered a species that was so different that we just had no way of relating to them. At least with minorities here on Earth, we share the same basic human template. For all we know, aliens will look, think, and feel things that are beyond our abilities.

Now, I know that scenario sounds bleak, especially for someone who claims to have more faith in humanity than most. However, there’s one last caveat that further complicates the issue and it has to do with the last part of my answer.

When I stated that the human race is not ready to encounter an advanced alien species, I mean that within a specific context. In the same way I don’t believe humanity is ready for advanced AI at the moment, I don’t think the collective psyche of the human race is to a point where we can accept the idea of confronting an intelligent alien civilization.

That, I do think we’re more ready today than we were 30 years ago. Humanity has made remarkable progress with respect to technology, society, and general welfare. Being more connected through media, the internet, and globalization has helped us better see ourselves as one species, at least to the extent our inherent tribalism will allow.

I believe that in the coming decades, especially as we augment our brains and our bodies, we’ll be more prepared to encounter an extraterrestrial intelligence. I’m not sure we’ll ever be completely ready, but I do think we’ll get to a point where we, as a society, will be able to handle it.

Whether or not that point comes within my lifetime or that of the kids being born today is hard to say, but given enough time and continued progress, I believe we’ll get there. For now, though, the prospect of encountering an intelligent alien civilization would incur some pretty detrimental effects on our species and our world. Even if aliens come in peace, we just not be ready to accept it.
