If Extraterrestrials came down and asked you for one reason why they shouldn't annihilate the human race....

requesting my permission means they have moral objections to just blasting us out of space without telling me so first.\n\nin asking me, they transfer the role of moral decider of our racial worth to me. of all people. they pick me. i suppose at random. the doofuses.\n\nso i would say....\n\n"the reason is, alienboy, that your race, although advanced, has lost the cajones to make military decisions. now hand me that antimatter cannon, its our turn to conquer space."

I don't think he is that stupid to start wiping out the human race no matter what the differences in opinions are, all over the world. I think that our leaders in the arm forces will question the launch of such a weapon of mass destruction.

The more powerful among us will try to use these aliens to increase their power for their own personal gain, for the more powerful among us are the most greedy.  In the end, the little guy will suffer, as he has done throughout history.\n\nIt will seem that we are not content with only destroying our own world, our own civilization, we will attempt (maybe succeed) to take advantage of these space aliens, use them, abuse them, squeeze them like a sponge to extract any information they can.\n\nI may not agree with what they will do, but I defend to the death their right to do so.

WTF?\n\nWhatever dude.  This does not even deserve a reasonable response.  Everyone knows that aliens did it as revenge for the UFO we shot down at Roswell.

why are u posting this in the astronomy and space part of a science and mathematics section of this site when clearly its a religous/cult/retard that needs a life question?oh ya  roswell doesnt have shit even if it was aliens what does that matter.what if the government was protecting from something that would make life horrible and completely worthless.

Lets assume five things:\n1) Aliens are extremely advanced.\n2) These aliens have the technology to travel through space.\n3) These same aliens wish to study us.\n4) These aliens have catch and release laws / ethics.\n5) Finally, these aliens do not want to be detected.\n\nIf I need subjects to study and I cannot just dispose of them, I want to pick subjects whose report of me is going to be discounted as 1) a dream, 2) a hallucination due to drink / drugs or 3) someone who is just plain dumb.  Or even better some combination of the three.\n\nThis way I get to study silly earthlings, and as my subjects report me and the tests I run, you all laugh and joke about him / her being a dumb hick.  Meanwhile I have hundreds of years of data accumulated.\n\nJust my thoughts.

Exterminate them.They are not fit to be called human beings.

That you were a terrorist getting ready to blow up the building and kill lots of innocents. That's what you wanted to hear, right, in order to re-enforce your belief that ALL Americans are racist neanderthals?

If there are aliens out there, I'd be willing to bet they won't contact us until we've stopped killing each other in silly little wars. After all, would you risk "warp drive" falling into the hands of us Klingons?

that is funny.  someone saying "Why would you believe a race of aliens without question?? Just because they have traveled through space doesn't make them trustworthy."  why would you believe a book just because it was written along time ago?

Well, I certainly wouldn't have to worry anymore about whether or not I turned the coffee maker off! Seriously, if the Earth stopped spinning on it's axis, there would be much larger factors at work & I'd be looking for the quickest way to get out of what was going to become an extremely unstable area of space! After all, assuming that I had a craft capable of long range travel, it might be left up to myself & whomever else might also be out on other missions to find a way to carry on the human race :)\n\nWhen I read the question the first thing I thought of was, "Pause.......BOOM!"

but about that alien invasion thing.... just had to give you my answer.\n\nIn order to wage war, you have to have good transportation and supply lines.\n\nSo far, we seem to have been out of the range of any possible space aliens.  You need to be able to get here first.  So they must not be close enough to be able to wage war.\n\nIf aliens wanted to take over our planet, it would be easier to redirect a large asteroid and kill all life on the planet, then come back later when things calm down.\n\nBut if they wanted to attack and steal our women, like in a 30's B movie, they'd have to employ more subtle means... like disguising themselves as Metrosexuals... ever wonder where they came from?  Me 'n Bubba think they're from Alpha Centauri...\n\nhoo hoo ha ha ha ha ha!!!!

If there IS an Area 51 and aliens DO exist at it... would you want aliens roaming the world?\n\nThat's exactly what would happen because upon proof of existence, every Rights group out there would declare that Aliens being locked in Area 51 is inhumane. Maybe even an Alien's Rights Group would be formed. ARG!

An alien invasion.  Like in the movies I think if Earthlings had a common enemy then they would be peaceful to each other.

It would destroy the Earth. And I'm not being facetious.\n\nIt would destroy the Earth in many ways. First, it could actually break the crust of the planet. This alone could break us into multiple pieces.\n\nLet's say for sake of argument that you set it off in a place that isn't seizmically active, and you just blow away a big chunk. More nastiness ensues.\n\nSecond, the dust cloud would encircle us, and the temperature would drop. Instant ice age, everywhere.\n\nThird, the Earth is remarkably fragile. We're exactly the right distance to be warmed by the sun, but far enough not to be cooked by radiation. The hole created in the atmosphere would remove that protection.\n\nFinally, our orbit will be thrown off. Maybe not enough to be thrown into deep space, but enough to make us tumble in scary ways.\n\nBasically, the end of the world as we know it.

Yes, alas, all things must eventually come to an end, especially the good things. Earth will indeed be destroyed eventually by some asteroid with our name on it. One such asteroid has been found: 99942 Apophis, which we still dont know if it will indeed strike the Earth in 2036. But, it isnt the proverbial dinosaur killer, its only 820 feet across, a peanut compared to others that have hit. But, yes, we could terraform Mars and turn it into another Earth, the way it was so many thousands of years ago. I mean, we can grow food hydroponically, create our own little magnetosphere, and create the feeling or effect of gravity. The problem with terraformation is that we have no idea how long it would take, estimates have ranged from half a decade to an amount that is not realistic. Yes, we would go there by spaceship unless the Gov. reveals its Stargate program or some other means of transport. I would assume that a large majority of people would go, but there are always gonna be the fanatics and those who would rather die where they were born. And, you cant realistically transport EVERY human off the planet unless we had many, many, many decades of warning, which we may not have. Sorry to be pessmistic about it, but the numbers just dont really work out in our favor unless we have the benefit of time. But, I would imagine that a majority of the people would make it off, because I would assume that in that realisation, costs would be waived. And imagine the chaos that would grip the globe! But its all very possible to do, we could go right now if we wanted to. And for those who didnt go... It would not look pretty. We're talking about water being flashboiled, tons and tons of rock and ash being thrown into the atmo. if the initial blast doesnt kill you the ensuing volcanic nuclear winter would. Crops would be destroyed and we've learned that nothing with a body weight of over 60 lbs made it through the last ice age. Those who stay behind... Their future would be very grim.

Anything's possible. It has been theorized that humans were the slaves of an alien race and left to populate the earth. Plenty use Egyptian mythology to base their answer, and actually do so quite effectively. So sure, why not?
