What If We Seeded Life on Another Planet? | Unveiled

What If We Seeded Life on Another Planet? From our position in space, life seems pretty
rare. So rare, in fact, that “life on Earth”
is as much as we can account for. We’ve now been searching for extraterrestrials
for decades but, so far, we haven’t found any. If life really is as uncommon as we so far
suspect it to be, then is it down to us to ensure that it continues and spreads? This is Unveiled and today we’re answering
the extraordinary question; What if we seeded life on another planet? Are you a fiend for facts? Are you constantly curious? Then why not subscribe to Unveiled for more
clips like this one? And ring the bell for more fascinating content! How did life come to be on Earth? There are a range of theories, including the
idea that we emerged out of a primordial, prebiotic soup billions of years ago, as well
as other proposals which argue that maybe it didn’t actually start on this planet
at all. The Panspermia Hypothesis suggests that life
on Earth was seeded here via organic matter brought from elsewhere by asteroids and meteors. Regardless of how we got here, though, Panspermia
is an idea that could feasibly affect us at the other end of the debate, too – we could
become the ones doing the seeding. In fact, we may have even done so already. The Voyager probes, humanity’s furthest-flung
machines in space, for example, weren’t sterilized to today’s higher standards when
they were launched out into the cosmos in the ‘70s. And, given all of the space missions we’ve
seen in just the last few decades, there have already been countless moments when germs
and microbes from Earth may have been unintentionally sent toward other planets, moons and asteroids. Even today it’s possible that there are
thousands of cells still alive somewhere on the Voyager crafts, ready and waiting to rest
and multiply on some other distant world in the future. To some extent, accidental Panspermia goes
hand-in-hand with our desire for space travel; it’s arguably unavoidable. But, were we to purposefully seed life somewhere
else, then what would be our motive? Well, for one, the continuation of the human
race. As we aim to venture further out into the
solar system, we do so in part to find other planets that are like Earth or that can be
terraformed to become like Earth. And, in a worst-case scenario where the real
Earth for whatever reason becomes uninhabitable, then humanity can survive on whichever planets
we’d most successfully adapted to meet our needs. Therefore, the planets most likely to be seeded
are probably also those closest to us and those most likely to be deemed habitable;
with Mars being a leading contender. Variations on the Panspermia Hypothesis even
theorize that we – the human race and all of Earthly life – are originally from Mars,
brought to this planet thanks to seeding from there to here around four billion years back. If that were the case then with Mars we’d
only ever be re-seeding our first home! Looking further afield, we might also try
seeding life on the Jovian moon Europa, which is arguably the solar system’s leading candidate
in terms of its potential to host life. Or, at a future time when the vast distances
of space are more manageable to us, we could choose to facilitate Panspermia on any of
the other possibly habitable exoplanets we’ve so far discovered. Beyond it offering a chance for humanity to
extend its life in the universe, seeding a planet could also have broader research applications
too; enabling us to find out more about the evolution of life, to see how complex organisms
come about in real-time, and to study how life adapts to extreme conditions. It could give us greater knowledge than ever
before about our place in the universe and how we came to be. But, that’s not to say that we should just
go ahead and seed humanity wherever we can and as soon as possible! It’s not all good or even encouraging news…
and there are already rules in place to avoid contaminating alien planets. We don’t want to introduce life and disrupt
an existing extraterrestrial ecosystem; we also don’t want to accidentally seed life
on another planet that we could later mistake as having originated from that planet; and
we don’t want to cross-contaminate during a return mission, thereby losing track of
potential alien microbes that we could also be redistributing. Today, you can work for NASA as a Planetary
Protection Officer, whose job it is to ensure that these practices are followed. More than over-cautious science, there’s
a major ethical debate at the heart of this question, too. Say humans were to one day arrive at another
planet where they know simple life already exists or they don’t know for sure that
it doesn’t… any deliberate attempt to seed our own strain
of life could alter the evolutionary path and disrupt the nature of that other world. One way to sidestep the “great unknown”
of sending humans anywhere that might (or might not) harbour life could be to use artificial
intelligence, instead. Theoretical Physicist Claudius Gros has proposed
seeding life through what he calls the Genesis Project. The idea is to have purpose-built probes carrying
organic material sent to alien worlds, but each probe is controlled by an on-board AI
which can reliably determine whether life already exists from afar… If it doesn’t exist, then the probes are
deployed; if it does, then they’re not. For Gros, the AI tactics could then be prolonged
to help the microbes that it does let loose to fast track into more complex life forms…
leading to a future time when humanity can safely seed and monitor life across multiple
galaxies, without ever traveling to most of them itself. It’s hoped that a Genesis Probe could even
be built and in operation by the end of the 21st century… so, watch this space! While something like the Genesis Probe would
afford us a degree of control, however, if we really were to seed a planet then we could
expect all kinds of new and unique creatures to spawn in time. Life generally adapts to its surroundings,
with Earth hosting millions of species itself, but there’s really no telling what kinds
of adaptations would take place to align with a never-before-seen, alien environment. In this way, a planet-seeding project could
go further than simply discovering whether life itself is rare, by determining whether
intelligent life is also something which can be replicated. For some, intelligence is the logical end
goal for all evolution, while for others it’s more an extremely unlikely and uncommon occurrence. Is humanity simply one stage in unstoppable
progress, or are we purely the product of a long-winded coincidence? Were we to seed a new planet from scratch,
then we could begin to answer that question… and, in the event that another intelligent
species did arise over time, then we’d have an interplanetary link all of our own making;
but one which could cause problems in the future. Were the beings we had seeded to discover
their human creators then they could come to see us as something like Gods. Equally, though, they could come to resent
those on Earth, or life on Earth could come to resent them… especially if their intelligence were to ultimately
surpass humanity’s own. On the one hand, we could forge an alliance
and work together to seed more planets in much the same way; on the other, we make an
ultra-advanced enemy of each other. But, either of those outcomes is a long, long
way into the future. For now, human-led Panspermia is a thought
experiment only, and not something we’re truly at risk of carrying out right away. Hypothetically, if humanity ever was faced
with extinction on Earth, then it really could be our only hope for survival; meaning our
end wouldn’t necessarily be the end of all life. Similarly, if we ever do hope to live on other
planets, then it could be a crucial part of our early plans. There are major ethical questions at play,
but that’s what would happen if we seeded life on another planet. What do you think? Is there anything we missed? Let us know in the comments, check out these

  • edmund paradero says:

    if common sense does exist then anyone can presume that indeed there is a planet like earth on other universes, it's the distance of earth from these other planets that make it impossible to say that there actually is/are planet(s) like earth, it's religion that strictly males it impossible for other habitable planet(s) to exist. either ways, moving to another habitable planet will not be an easy thing since here on earth the idea of there are aliens give some people the creeps, what more on the inhabitants of other planets, after all we will be alien on their planet, just saying my thoughts… peace!

    Hi everyone

  • KingD says:

    To be completely honest
    There is zero reason we shouldn’t be doing this

    -I watched this entire video, heard all the “downsides” and it baffles me that a worry exists like “what if they get more intelligent” like bro… it takes millions upon billions of years for evolution to even produce multicellular life then full animal like life forms. Then you have to consider all the time and stuff that has to happen for intelligence. By the time caveman level intelligence would exist on anywhere we seed we would already be millions/billions of years more advanced then we already are. We have legit literally nothing to worry about

    If we want to seed life on another planet we should shit on it. I'm not kidding. The bacterium in feces is exactly what you need to start viable soil. Other things you should add are lichen, pond scum, and dead animals.

  • Eman Name says:

    It's a very idealistic idea. Why should humans seed life on another planet if they can't even keep this one from spiraling into a global runaway greenhouse? Then there's wars, greed, power madness, inequality, subjugation etc. So ideally if we had it together it could be a sensible proposition but at this point why bother spreading humanity's destructive influence to another world.. think of the bigger picture and you see the futility of it.

  • Mortimer Hasbeengud says:

    until we hit FTL (whenever), I would guess we need do this (if uninhabited) using advanced nanotech likely due later this century. It can do the job theoretically, depending what sort of life the grand kids, desire on Proxima Centauri 6 or whatever they choose. Maybe carbon, maybe silicon life, maybe electronica? Above my pay grade however we will seemingly hit there with, this century.

  • Susse Kind says:

    The Israeli craft that was carrying tardigrades to the moon, crashed. Very possibly spreading tardigrades all over the lunar surface.
    Now granted, the tardigrades were in a tun state (dehydrated). However, if you were to look for the hardiest animal to survive in space or on another planet, a tardigrade would be it.
    If life has even the slightest chance to grab a foothold, it will. Then it will do what it does best, live.
    Panspermia from earth, whether intentional or not, is inevitable if we continue into space.

    If we have the ability to seed life on another planet that would mean human origins may come from another planet who did the same to our planet in earth’s early days. A once intelligent life form made sure that life in our solar system continued before something wiped them out

    Heres an idea when we make far spacetravel rockets or ships lets take eggs and sperm and make a machine that would birth new generation about 20years before arriving to a new planet and there would be either androids or just some machines that would teach everything they need to know to colonice a planet and all the science we have

    Ha! How can you seed another planet when having a hard time procreating on your natural planet Earth!

    Why dreaming! We will never reach another planet outside our own planetary system! Even that is more or less a fantasy!

  • Nwabueze Ozuzu says:

    What if we were seeded here by another highly advanced race that located this planet and calculated the conditions here to support life?

    What if we seeded Earth from Mars? I do believe that "we" arrived from "there"? The idea of life evolving on Earth from Anaerobic and aerobic conditions is so obsolete.
