When will aliens kill us all?

Answer 1

(I think) Stephen Hawking said that the history of advanced civilizations meeting primitive civilizations has not been nice.

I think it is impossible. This situation like when we meet other people of other ethic. If we do not harm them, there no reason for them to kill us. Except when they have a plan to kill the human for something that benefits to them. (If they exist in somewhere).

It's hard to say. They might be quite friendly, it's just, according to the media, they're usually not.

Of course, the media exists to sell you stuff, and so it is in their best interest to stir people up and get their attention!

There is no mineral wealth available on Earth that could not be found floating around in space, with no one to fight with for it. That includes hydrocarbons. Water and ammonia (for fertilizer) is also free for the taking. That leaves only one thing you can find on Earth that you can't get for free elsewhere... life. And it makes no sense at all to chow down on humans, who take 18 years of high quality care to get to maturity, as opposed to cattle, who don't. Oh, and cows don't fight back, either. So the smart thing to do if you need food is to snag some cattle or cattle DNA, and crank out cows where the food is actually needed.

So there is no reason why aliens would come all the way here, past the immense mineral wealth of the outer solar system, and kill people.

Liquid water is not plentiful. only here on earth that we know of. But if you have the tech and power to travel the stars, you can melt ice. In fact, ice travels best as ice. Melting and keeping it molten takes power, and the only "benefit" is that it can then leak!

Answer 2

No intelligent aliens (beings not native to earth) have been discovered so far. No one knows if, let alone when, an alien invasion might begin.

In the case of aliens who are native to earth but not to the country in which you are located, if you are in the Western Hemisphere an "alien invasion" has been going on for about 500 years.

Answer 4

Aliens are not known and proven to even exist, let alone be mean.

Answer 5

I'm afraid that aliens have long since taken over the earth. Only alien creatures would waste, pollute, and destroy a beautiful planet like earth. They're known as humans.
