Would Aliens Die on Earth? | Unveiled


Could an Alien Civilization Survive on Earth? H.G. Wells’ seminal science-fiction novel
“The War of the Worlds” tells of an apocalyptic invasion of Martian war machines aiming to
eradicate the human race. And ever since Wells set the tone, we’ve
seen a slew of similar, end of the world stories where humanity seems certain to fall to an
extraterrestrial foe. But, is our planet really so vulnerable to
alien invasion? This is Unveiled, and today we’re answering
the extraordinary question; could an alien civilization survive on Earth? Are you a fiend for facts? Are you constantly curious? Then why not subscribe to Unveiled for more

as the aliens and explore how we would function on another planet. Our own prospects do rely heavily on the kind
of planet we’d be going to, but considering just those that are closest to us, the outlook
isn’t all that encouraging… we more than likely wouldn’t survive, unless we employed
some elaborate terraforming technologies to build advanced space stations or to precisely
mimic Earth’s environment. It’s why the search for planets already
“Earth-like” in the wider universe is so important. But, even were we to stumble across a world
with just the right atmosphere and temperatures naturally, the threat of disease would still
be very high. We’d have little idea what sorts of pathogens
and poisons might lurk on an alien world… To the point where we could spend decades
running interplanetary reconnaissance missions before we ever sent an actual human to visit
anywhere else – just look at how seemingly “slowly” we’re already studying Mars! It’d be no use just “turning up” and
expecting an extraterrestrial environment to be safe for us… so any aliens visiting
Earth, friendly or hostile, would almost certainly be faced with the same issues. Should they be invading Earth, they’d have
had to have done their homework beforehand or else risk their invasion failing from the
moment they arrive. But, equally, if they “came in peace”,
they’d require as close to a complete understanding of Earth’s properties before showing up. Perhaps they would stand more of a chance
if they arrived with good intentions, however… as we could always decide to help them. A risky move, perhaps, but by welcoming and
assisting them we’d also have the opportunity to build an enlightening relationship with
a unique, intelligent, and advanced space-faring species. For us, it’d be the ultimate in scientific
case studies and could even accelerate our own ambitions with space and interstellar
travel… granting humanity access to proven alien tech and intelligence. Meanwhile, for the aliens, striking a positive
link with the inhabitants of the planet they’ve just arrived at could truly be the difference
between living and dying. With humans acting as guides they’d at least
have a better chance of understanding and reacting to conditions on the ground. By helping them to survive here, we could
be better placed to survive somewhere else. But, while a well-meaning and productive relationship
between us and an unknown otherworldly race sounds fantastic… just plain human history
tells us that it’s not all that likely to happen, with even Wells’ “War of the Worlds”
partly inspired by various conflicts in time. The very fact that an extraterrestrial lifeform
had managed to get here from some dim and distant star system would reveal a phenomenal
level of technology and know-how – far superior to anything we could offer. So, if they did also carry weapons or harbour
any type of aggressive intention, then the chances are that we wouldn’t be able to
defend against them – despite holding “home advantage”. In terms of; “Could an alien civilization
survive war on Earth?”… the answer’s almost certainly; “yes” – if technological
superiority equates to victory on the battlefield. Such a conflict may not even play out on Earth
itself, however, with potential alien aggressors preferring to target our planet from afar
– deciding to circle Earth rather than descend down onto it. Regardless of the intentions they hold, a
delayed approach like this could well be key for their chances of survival. It’d allow an alien race time to scope out
Earth before putting themselves at the mercy of it. For all-guns-blazing conquerors, it’d open
a window to remove all Earthly life which poses a threat to them; for peaceful visitors,
it’d provide enough time to work out a way to communicate with their human hosts. For both cases, the next move would be to
send mechanical probes and rovers to the surface to further avoid any potentially irreversible
biological risk. Because, more than anything else, the biggest
threat to an alien civilization on Earth is still disease. Organic life on Earth has been around for
millions of years and remains, to this day, susceptible to sickness and infection. There are devastating illnesses not even we
have reliable cures for or vaccines against… And, with the World Health Organization now
listing antimicrobial resistance as one of the most significant threats to modern life,
the preventative measures we do have in place could soon be less effective. For an incoming but ill-adapted alien race,
then, even our relatively routine problems – like the common cold, for example – could
prove deadly. And, as many of our vaccines rely on herd
immunity – meaning lots of people need to have them before they work – an alien race
could well fall foul to nature before anything else. All of which means that, if war were to break
out between us and them, it’d most likely be a fight fought with biological weapons,
rather than nuclear. But, even then, as human history also shows
just how quickly whole communities can be wiped out when exposed to a previously unknown
disease, we’d be as susceptible to an “alien plague” as an extraterrestrial race would
be to our own germs and bacteria. The problems an alien civilization would face
on Earth are theoretically very similar to those that a human colony would face elsewhere
– the only major difference being that we obviously know there’s life to contend with
on our particular planet. In general, they’d need to be sure that
they could survive or adapt to Earth’s most fundamental, atmospheric conditions; they’d
need to be able to feed on whatever it was that gave them life; and, if the situation
was to turn ugly, they’d have to withstand whatever weapons the human race could aim
at them. It’d be a tough ask, but if anything ever
manages to travel all this way, then we can only guess that they’d have all the bases
covered to stay long-term! What do you think? Is there anything we missed? Let us know in the comments, check out these
