5 Ways Aliens Could Invade the Earth and How We Might Stop Them
The Imminent Alien Invasion
Could aliens really invade the Earth, and if so, how would they do it?
A life form capable of traveling countless light-years to get to our planet would be far superior to us and likely possess technology we can barely comprehend. In the movies, the humans always come out on top when aliens come looking for trouble, but in reality, we'd be doomed.
Or would we? While an alien race that traveled to Earth would certainly have knowledge of some seriously hardcore science that would enable them to make the journey, that doesn’t mean they are superior to us in other ways. Just like that nerdy kid from high school who aced advanced trigonometry but couldn’t bounce a basketball without knocking himself out, aliens may be all brain and no brawn.
In that case, we may have a fighting chance. You can say a lot of negative things about us humans, but when it comes down to it we are fairly stubborn and tenacious life forms. We fight tooth and nail against each other, so any invader coming down to this planet with bad intentions certainly will not get a warm welcome. In fact, they will probably get a left hook to the jaw. Or to the pincer. Or whatever.
The possibility that aliens will invade the Earth someday is more real than people may think. Of all the supernatural beings alleged to exist, alien life is the only one that is not only plausible but likely. Our galaxy is estimated to hold some 300 billion stars and 100 billion planets. Surely some of those planets support life, and some of that life is intelligent.
The real question is whether or not that intelligent life is capable of coming here. So, what can we do if they decide the Earth is theirs for the taking? Here’s a look at some of the ways aliens could invade Earth, and how we might stop them in their tracks.
An invading force from another planet may attempt to conquer the Earth with a military attack.
All-Out Alien Attack
Aliens may invade the Earth by launching a military-style assault in an attempt to annihilate us. Who knows what tactics they may employ, but taking out our communications satellites seems a logical first move. Then, they may deploy EMP weapons in the atmosphere to disable our electronics systems.
The third step might be a massive bombardment of the planet by their warships in orbit around the Earth, with the purpose of destroying major cities and population centers. Finally, ground forces and tactical aircraft will mop up any remaining humans that pose a threat.
If their technology is sufficient we may be helpless against such a military strike. However, there are two possible scenarios where we might win out over a superior enemy.
In the first, we have to hope they are unable to do serious damage to our population centers and military capabilities with their initial cannonade. In this case, some of the most powerful countries around the world such as the United States, Great Britain, Russia, Australia, and China may be able to hold their own against alien ground assault troops. The invaders may have better technology, but we are on our home turf and our military forces are very good.
In the second scenario, humanity is reduced to fighting a guerrilla war. It isn’t likely an alien occupying force would be able to completely exterminate humans by brute force, at least not in a short period of time. Pockets of resistance around the globe would continue to fight back and try to send the colonizing bullies back to their home planet.
In either scenario it is not likely we would defeat a superior alien enemy in the long run, but we don’t have to. We only need to hang in there and cause enough havoc for the invaders to realize that taking the Earth isn’t worth the loss of alien blood and treasure.
With a little luck, if we can make things tough enough for them they'll pull up stakes and look for an easier target somewhere else in the galaxy.
Aliens may release a biological weapon causing a worldwide pandemic.
Release of an Manufactured Pathogen
If an invading force wishes to take over the Earth they may be able to do it without ever firing a shot. They may be able to engineer a pathogen and unleash it on our planet, making a deadly disease do their work for them.
Really, in this scenario invading aliens wouldn’t even need to make their presence known to us. For example, if they had the technology to do so they’d simply need to harness an asteroid or comet, load it up with some anti-human virus, and launch it at the Earth.
From our point of view, we’d see an asteroid impact followed by the outbreak of some strange pandemic that gradually spreads across the world. As our population dwindles and our societies erode it may never occur to the last humans alive on Earth that we have been the victims of an attack. Once we are gone, the invaders move in.
Sounds grim, but surely super-intelligent aliens would choose a method such as this over military conflict. So what can we do?
Our only hope would be for our scientists and researchers to come up with a cure for whatever disease the aliens concocted. Maybe they’d be able to tell it is something made in a lab, but really smart aliens may be able to make it look like a naturally-occurring mutation of a known Earthly virus. In any event, cures and vaccinations would be our only chance at survival.
Some sections of the population may prove to be immune, and very remote human populations may be spared simply by lack of contact with the outside world. So, humanity will go on, but with the way the world is linked together by air travel today it is likely a successful biological attack would mean the loss of billions of lives.
What are the Chances of Intelligent Life in the Universe?
Aliens could use technology to turn the Earth against us.
The Invaders Take Control of Nature
Aliens may be able to turn our own planet against us. By manipulating natural forces such as weather patterns and plate tectonics other-worldly intruders would be able to destroy huge numbers of us along with the infrastructure we depend on for survival. Here is another scenario where we would likely have no idea that alien forces are at work.
Asteroids would batter the Earth. Massive tidal waves hundreds of feet tall would crush our coastal cities. Earthquakes would crumble major population centers. Tornadoes would carve wide swaths across the landscape, demolishing everything in their paths. Hurricanes would wreak havoc along the coastlines.
As lost lives pile up and the cities crumble the remaining population would endure the constant burden of rebuilding roadways, restocking food supplies, keeping the power grid working, and maintaining communication systems.
After months or years of a constant battle with the elements, the remaining human population would be back to living conditions something like those of the Stone Age. There would be no more advanced technology to rely on, and no resources beyond what we could get from the natural world.
So how would we prevent our extinction in such a scenario? Aliens may be able to wipe out millions, even billions of us by controlling the weather, but ultimately their plan must depend on the resulting chaos when our world is suddenly plunged back to a time when there was no electricity, functional government, or communication systems.
Certainly, everybody won’t make it, but those humans who are able to adapt to a new world and relearn the skills that allowed us to thrive on the savannahs of Africa, the steppes of Central Asia, and the plains of North America may have a fighting chance.
While we may lose our technology in the short term, and end up in a dark-age of sorts, certainly there would be those who remember the science and technology that once made our species great. Once the invaders ceased their campaign of destruction and began to colonize the Earth, the stage would be set for a human uprising and a retaking of the planet.
An alien invader may use threats to coerce world governments into turning their people into forced labor.
Intruders May Intend to Enslave the Human Race
What if aliens didn’t want to destroy us at all? What if they need us? If their interest in the Earth is not for colonization but for mining its resources it stands to reason they would need a labor force to do the work for them. With sufficient technology, a relatively small number of them might be able to take control of the Earth, but they would still need us to do the dirty work.
But how would aliens force nearly seven billion people to do their bidding? Ruling out some mind-control method where we all suddenly line up and start packing water to be shipped to Zeta Reticuli, one possible way would be through threats.
Perhaps an invasion force would suddenly appear on our doorstep and make it known that unless we provide them with what they want they are going to blow our planet to smithereens. Uh, give us a minute to think about it, we’d say.
Debates would rage around the globe. Where did these guys come from? Are we willing to part with our resources? Could we take them in a fight? Their ship looks pretty cool, don’t you think?
If dirty rotten aliens are anything like dirty rotten humans, they’d probably throw a little manipulation in there with the threats. Give us a thousand tons of water and we’ll spare your planet, they might say.
After much debate, and with the total annihilation of the human race a real possibility, Earth leaders might agree and set up a system for collecting the water and sending it to the aliens.
Of course, the intruders wouldn’t stop there. They’d have us right where they want us. The demands for resources and the threats would escalate until we did little more than eat, sleep, and gather resources. We would be, effectively, enslaved by an alien invader.
The way to defeat such an oppressor is the same as it has always been: Brave people must stand up and fight back, refuse, resist. Eventually, if we were to ever again have hope of being anything more than worker bees, we’d have to start swinging.
Many people won’t survive the fight, but if we can prove to be too unmanageable for our alien handlers they may decide we aren’t worth the aggravation. It would be a long shot, but the only hope we’d have.
Aliens might bring about the extinction of humanity by altering our genes.
The Gradual Degradation of Our Population
Aliens who are intent on invading the Earth may choose to alter our genes as an easy way to wipe us out. For decades believers have said UFOs have been abducting people and conducting experiments. Even if they aren’t, the possibility exists in the future. What if the intent is to weaken our species by altering our genetics so we are more susceptible to disease, or so that all humans are eventually sterile?
Slight differences in our genes determine our individuality as humans, and the traits we will pass on to our offspring. Because of their genetic traits, some people are more likely to get cancer, less likely to have kids, or more likely to play professional basketball straight out of high school, among millions of other possibilities. What if aliens found a way to ramp up all the bad things we could pass down to our offspring?
This would be a program that would span hundreds if not thousands of years, but let’s assume these aliens are patient. Or, let’s assume they have the ability to move back and forth through time. If they let it play out, eventually they could eliminate the entire human population simply by altering our genes.
With nearly seven billion people in our little world the invaders would have their work cut out for them. But unlike with other methods of invasion, they wouldn’t have to annihilate us on a grand scale. They would only need to tip the population trend in the other direction. Year after year of declining births and increased deaths would eventually take their toll.
The good news in this scenario is that now-living humans would not have to battle alien troops, endure a pandemic, survive endless natural disasters, or go to work mining resources for oppressors. The bad news is, eventually humans will become extinct.
So, how could the human race survive? Presumably, once a decline in the population was detected on a serious level our scientists would set out to discover the cause. Perhaps our understanding of genetics is already sufficient to create our own program to reverse the trends. Or, new programs could be implemented so that the healthiest humans could pass on their genes.
Engineering human genetics is always a controversial subject, but in the face of extinction, it may be a necessity.
Hope for Humanity Against an Alien Oppressor
These are just five of the possible scenarios of how aliens will wipe out humans and invade the Earth. Certainly, there are many more, some more hopeless than the ones in this article. Would humanity survive any of these events?
It’s not likely, but there is hope. Humans are aggressive, belligerent, stubborn, and selfish. These are the traits that have led to all the wars ever fought, all the atrocities ever committed, and all the conflicts that exist in the world today. They are also the human qualities that might make any alien invader wish they had stayed home.
But these aren’t the traits that make us human. In addition to the negative aspects of our humble race, there are many good things about us as well. Humans are compassionate and will go to great lengths to protect people they don’t even know. Humans are independent and will fight against injustice wherever it is found. Humans are tenacious and will keep swinging until the bitter end.
Planet Earth belongs to humans and all of the animals and plants that call it home. But it is also the only planet in the known universe guaranteed to provide all of the resources needed for life to thrive. Sooner or later, it could attract the attention of alien invaders with bad intentions. Will we be ready for them?
Will they be ready for us?
