If aliens suddenly attack Earth, how long can we defend ourselves?

Human beings are currently unable to discover extraterrestrial life at the current level of science and technology, and the level of human science and technology is currently at a relatively low level of civilization. If aliens suddenly attack Earth, proving that aliens can carry out interstellar travel, their technological level is much higher than that of humans, in this case, humanity will be defeated.

Maybe you can't resist it for ten minutes, if aliens invade the earth, then their technological level is not at the same level as us, and their invasion of us is equivalent to a dimensionality reduction strike.

It can't be resisted, if aliens can attack the earth, it means that alien technology is much higher than ours, and humans are like ants.

For a long time. Because human beings have advanced **, and there are also powerful armies, we can resist for a long time.

If aliens attack Earth, will the Earthlings have the ability to defeat each other? This is a good question, first of all, any strategy is useless in the face of absolute strength! Now, if the aliens can come, it means that they have mastered the ability of interstellar travel, whether in theory or technology, I don't know how many levels higher than us.

It's almost like the modern United States fighting ancient Egypt, and it may be even more far from this. Even fight the primitive tribes like that! Their computers are also indescribably powerful.

In a few days, the holographic solar system, any move we make, any movement of any person will be mastered! So how to fight? Only lose.

In terms of technology, there is no advantage, because we have not found aliens for so long, and they can find us, which means that they have an advantage in technology, which basically crushes us; Unless we have something to restrain their weaknesses, similar to the aliens in the movie Pacific Rim who are afraid of light, there are still some possible wins, but there is a high probability of losing.

The word invasion illustrates the fact that aliens have entered the territory of Earth and there is aggression, indicating that they are not in good faith. Since the first is not well-intentioned, and the second finds the human before the human finds the other, then they will not be unprepared, and the degree of civilization is very likely to be higher. There is little chance that humans will survive.

But everything depends on the comprehensive strength, the other party cannot be perfect, which means that there are shortcomings, if you can take advantage of the characteristics shown by the other party, there is still a chance of winning. If the other party directly destroys the earth, then I didn't say it. There is absolutely no way to win, if you can break through the limits of the universe, break through the shackles of light, and come to the earth, then our civilization is not at the same level, and all your technology is a child for them, so there is no hope of winning at all.

So it depends on their intentions, if it is malicious, we will definitely not be able to win, if there is no malicious, then naturally there is no problem, so it depends on the aliens, not us, the initiative is not on our side.

I don't think the earthlings have the ability to defeat each other, and if aliens can reach our planet, it means that their technology is quite mature, and then it may be a world war.

There is no ability to defeat at all, the combat ability of the earthlings is still relatively weak, and through some technology, they cannot be defeated at all.

It can be defeated. Humans on the earth can be said to be very powerful and very intelligent, so I think they can be defeated.

has the ability because earthlings are so smart in the first place, and they will also use some ** equipment when fighting aliens.

If aliens attack the earth, the earthlings are also capable of defeating the other party. Because the number of earthlings is very large.
