If aliens became aware of us, would they conquer/enslave/exploit/displace/exterminate us?

Our very existence might offend them, in some religious way - the fact that we don’t Splooon or Vlub might make us anathema to them.

Or our radio transmissions are futzing with their hyperSoapies reception, and they’re not standing for it.

They may have a need for planets of a certain type for other than economic reasons, like maybe they can only breed on Earth-like planets. Or are only *allowed *to breed on ELPs.

Maybe they’re environmental fanatics, like some species in Brin’s Uplift Universe, and they see killing us off to protect Earth’s potential as a sacred duty. Or to get at our dolphins and chimps for Uplift before we do.

Or they might just like hunting and killing new things, like that one ST:Voyager species (Hirogen?), Predators or the Affront in Bank’s Excession.

Then again, ETs might only want to study us out of scientific curiosity . . . which could be even worse . . .

If you became aware of E.T.'s, would you conquer/enslave/exploit/displace/exterminate them?

I assume an alien’s response to us would be much the same as our response to those tube worms living on undersea volcanic vents - that is, we’d show up in a their equivalent of an IMAX documentary, with aliens ooohing and ahhhing at how goddamn wierd and wonderful we are, and with alien scientists struggling to get grants to study us.

Enslavement, expoitation? Not a chance. No possible eploitation could be worth the huge trouble it would take to get here. If they somehow had godlike powers to transport easily, what possible worth could human slaves be?

I think that they’d use us for sex, food and entertainment.

They’re alien for gods sake, we have no idea of their thought processes, feeling or motivations.

Alien means just that, not a human with a brow ridge or pointy ears, who just happens to have only one of our human emotions in predominance.

For all we know they might arrive here and start worshipping a small, desert dwelling lizard .
Aliens can be so…alien sometimes.

If they want our planet, surely they’d just sterilise it and move in their own flora and fauna?

We’re the alien colonists, and our planet was colonized the only practical way for planets to get colonized - microbes.

What a ridiculous notion. Having the capability of galactic travel, why would they not just colonize any number of other planets that would be (presumably) unopposed?

Any alien species advanced enough to travel here would probably have the technology for advanced robotics – if they mastered computer science to the extent of humans – and the ability to mine other rocky planets and asteroids, regardless of atmosphere, for the resources they need. Why enslave humans? Also, there’s likely to be rocky planets with Earth-like atmospheres that don’t have sentient lifeforms living on them. If I were the leader of an alien race in need of “lebensraum”, and had the choice of settling on any of 50 habitable planets without sentient creatures, or one with humans, I’m going to go for the low-hanging fruit.

Just because Earth supports life doesn’t necessarily mean it will support alien life. It’s not just the atmosphere, but also temperatures, length of the day and year, and gravity. If the aliens originate from a planet with half the gravity of Earth, have a circadian cycle of 40 hours, and depend on crops that have a 300 day growth cycle, from germination to harvest, Earth isn’t going to be the place for them.

Any electro-magnetic signal broadcast from Earth would become too weak to distinguish from background noise long before it ever reached 140 light years. IIRC, it wouldn’t reach much beyond our solar system.

Math only has one solution, while as reason has many, but the total number of reasonable answers to any question is limited. An irrational answer is irrational regardless of anything.

A species that has been able to develop to travel outerspace in reasonable periods of time is most likely going to approach things rationally. You can’t develop to that point if you’re too irrational.

In S.M. Stirling’s Domination of the Draka AH/SF series, a human culture emerges dedicated to, well, what might be called collective self-actualization, through the conquest and enslavement of all non-Draka. They even develop a power philosophy about it, based partly on Nietzsche; and while a philosophy of that kind might be invented originally as a justification/rationalization of what the culture is doing anyway, it can come to exercise independent influence over the minds of later generations. In the fourth novel, Drakon, the Draka of the 25th Century are exploring nearby star systems and conquering/enslaving any sentients they find there, making them worship “the gods from the sky” – just because that’s what Draka do. It’s how they get interesting new toys, and they like having slaves truckle to them. They plan to conquer the whole galaxy eventually, however many millennia it takes; that’s what they see as their destiny.

It is not inconceivable there is a real-life culture somewhere in the universe that thinks like that.

I’ve found myself wondering what Stirling’s Draka would do, if they encountered an alien sentient race so utterly alien that any meaningful enslavement of it to humans would be imponderable. Such as the neutronium-based cheela of Dragon’s Egg, by Robert L. Forward, with whom even basic communication faces both physical and time barriers.

I rather suspect the Draka would try very hard to find some way to exterminate the cheela, simply because the existence of a free non-Draka race, anywhere, does not fit in with their view of proper order of the universe.

And, again, there might be an ET culture out there that thinks like that, and will kill us if, and because, they cannot enslave us.

Another example of this sort of thing is Olaf Stapelton’s SF classic Star Maker:

Briefly, the semi-omniscient narrator encounters civilizations who have created world-spanning utopias, and who in some cases seek to “export” their utopian systems to alien sentiences, for their own good and in the name of higher morality - in some unfortunate cases, the utopian ideal turns perverse, in that the prostletization of aliens takes on the nature of a jihad, which in turn taints the “utopia”.

All very unlikely IMO.

What, you think the development of high technology is enough to put an end to crazy-thinking?

From George Orwell’s 1941 essay “Wells, Hitler, and the World State”:

And yet, he very nearly did win. And are we not, even now, worrying about Iran developing atomic weapons and putting them in service of a neomedieval conception of Islamic theocracy?

Why not a jihad among the stars?

Time, distance and expense.

The Jihad may appear to modern sensibilities as purely irrational, but in point of fact it served many strongly rational purposes: it allowed what was originally a group of weak tribes living in a crappy desert to overcome and appropriate several centres of world-civilization for themselves.

The problem with a Jihad among the stars is that the stars are so damn far away. Unless our aliens can overcome the laws of physics, any trip among them is going to take many years, and involve vast expense. Notions of interstellar troopers descending on Earth for a Jihad seem IMO very unlikely.

It is possible that the aliens would lob what amounts to a grenade in our direction - a small probe with some bio-war agent or loaded with advanced nukes, or something more esoteric - but that, too, seems unlikely to me; we would no more be a threat to them, than australian aborigines threatened England circa 1780.

Probably; but, see post #53.

There was a thread recently on this, but what the hell, I’ll repeat myself:

I strongly doubt that aliens would want to conquer earth. If earth was of any value at all for extraterrestrials it would be to study our biology and culture; for curiosity only.

Because to travel here they would have to cover astronomical distances and expend astronomical amounts of energy, to get to somewhere that is a grain of sand on astronomical scales.
And, to cut a long story short, none of the reasons for them wanting this grain for themselves stands up to scrutiny IMO.

And that’s before you even start to consider how much the rest of their technology and society will have progressed by that time.
I see no more reason to suppose that they’d behave like the conquistadors than like cavemen.

If I understand Hawking correctly, he’s saying that since interstellar travel is so difficult, any species that could do it would almost have to be specialized as an interstellar horde or swarm, looting the resources of entire systems to build and fuel their next move.

Well, if we build power armor then we’ll be able to fight off the Posleen horde and keep them from putting us in their feeding pens as snacks…
